![String[] cars;
• We have now declared a variable that holds an array of strings.
• To insert values to it, we can use an array literal - place the values in a
comma-separated list, inside curly braces:
• String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
• To create an array of integers, you could write:
• int[] myNum = {10, 20, 30, 40};](https://image.slidesharecdn.com/computerprogramminglanguage-221003034227-bbe3d252/75/COMPUTER-PROGRAMMING-LANGUAGE-pptx-25-2048.jpg)
![• Access the Elements of an Array
• You access an array element by referring to the index number.
• This statement accesses the value of the first element in cars:
• Example
• String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
• System.out.println(cars[0]);
• // Outputs Volvo](https://image.slidesharecdn.com/computerprogramminglanguage-221003034227-bbe3d252/75/COMPUTER-PROGRAMMING-LANGUAGE-pptx-26-2048.jpg)
![String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
System.out.println(cars[0]);
System.out.println(cars[1]);
System.out.println(cars[2]);
System.out.println(cars[3]);
int[] myNum = {10, 20, 30, 40};
System.out.println(myNum[0]);
System.out.println(myNum[1]);
System.out.println(myNum[2]);
System.out.println(myNum[3]);](https://image.slidesharecdn.com/computerprogramminglanguage-221003034227-bbe3d252/75/COMPUTER-PROGRAMMING-LANGUAGE-pptx-27-2048.jpg)

- 1. COMPUTER PROGRAMMING LANGUAGE Instructor: SofiaV. Arquero JAVA
- 2. TOPICS: • Overview ofJava • Java Environment • Data Types • Variables • Declaration of Data types and Variable • Input output • Single array
- 3. JAVA • Java isa high programming language and computing platform first released by Sun Microsystems in 1991-1995. • Sun Microsystems developed the language in 1995 based on the syntax of C and C++. Today, Java is part of Oracle Corporation (Developer) • Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network and web applications
- 4. The small teamof sun microsystem engineers called Green Team • 1) James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. • 2) Initially designed for small, embedded systems in electronic appliances like set- top boxes. • 3. Developed a programming language called oak in 1995 was renamed to JAVA • The logo of Java Cup and Saucer comes from the Java Coffee
- 5.
- 11. What are theapplications of Java? • Java Mobile Applications. ... • Java Desktop GUI Applications. ... • Java Web-based Applications. ... • Java Web Servers and Application Servers. ... • Java Enterprise Applications. ... • Java Scientific Applications. ... • Java Gaming Applications. ... • Java Big Data Technologies.
- 12. List Of The10 Best Java IDE 1.Eclipse 2.IntelliJ Idea 3.NetBeans 4.BLUEJ 5.JDeveloper 6.DrJava 7.Greenfoot 8.JGrasp 9.Android Studio 10.JCreator
- 13. JAVA ENVIRONMENT • The Projectswindow, which contains a tree view of the components of the project, including source files libraries that your code depends on. * The Source Editor window with a file called HelloWorldApp.java open. * The Navigator window, which you can use to quickly navigate between elements within the selected class.
- 14. DATA TYPES Data typesspecify the different sizes and values that can be stored in the variable. There are two types of data types in Java: 1.Primitive data types: The primitive data types include boolean, char, byte, short, int, long, float and double. 1.Non-primitive data types: The non-primitive data types include Classes, Interfaces, and Arrays.
- 16. There are 8types of primitive data types: • boolean data type • byte data type • char data type • short data type • int data type • long data type • float data type • double data type
- 17. • A byteis 8 bits because that's the definition of a byte • Character sets used today in the US are generally 8-bit sets with 256 different characters, • Each character is stored using eight bits of information, giving a total number of 256 different characters (2**8 = 256).
- 18.
- 19. Program Examples: //integer -whole number int X=20; // float 6-7 digits decimal points precision float Y=15000; //double can give you 15-16 decimal points precision. double SUM=250000; //char is a letter char ch ='S'; // String is a sequence of characters String address="Muntinlupa City"; In Java, System. out. println() is a statement which prints the argument passed to it.
- 20. INPUT/OUTPUT STATEMENT • Scanneris a class in java. util package used for obtaining the input of the primitive types like int, double, etc. and strings. It is the easiest way to read input in a Java program, import java.util.Scanner; Scanner input = new Scanner(System.in); creates a new Scanner instance which points to the input stream passed as argument. Declaration: Data types and statement
- 21.
- 22. Solving a ProgrammingProblem. ... • Read the problem at least three times (or however many makes you feel comfortable) • Analyze and understand the problem • Use and declare data types • Use variables related to the problem • Do some statement • Process and Computation
- 23. ACTIVITY: 1. Write aJAVA program to grades of five subject and calculate the total average.
- 24. Array • Arrays areused to store multiple values in a single variable, instead of declaring separate variables for each value. • To declare an array, define the variable type with square brackets:
- 25. String[] cars; • Wehave now declared a variable that holds an array of strings. • To insert values to it, we can use an array literal - place the values in a comma-separated list, inside curly braces: • String[] cars = {"Volvo", "BMW", "Ford", "Mazda"}; • To create an array of integers, you could write: • int[] myNum = {10, 20, 30, 40};
- 26. • Access theElements of an Array • You access an array element by referring to the index number. • This statement accesses the value of the first element in cars: • Example • String[] cars = {"Volvo", "BMW", "Ford", "Mazda"}; • System.out.println(cars[0]); • // Outputs Volvo
- 27. String[] cars ={"Volvo", "BMW", "Ford", "Mazda"}; System.out.println(cars[0]); System.out.println(cars[1]); System.out.println(cars[2]); System.out.println(cars[3]); int[] myNum = {10, 20, 30, 40}; System.out.println(myNum[0]); System.out.println(myNum[1]); System.out.println(myNum[2]); System.out.println(myNum[3]);
- 28. ARRAY ACTIVITY: ARRAY 1. Writea Java program to sum values of an array.
- 29. • int A= 20; • int B=30; • • int banana=100; • int grapes=300; • int orange = 400; • int sum=0; • • • System.out.println("The value of A is" + A); • System.out.println("The value of B is" + A); • String address = "muntinlyoa"; • • System.out.println("address is" + address); • System.out.println("address is" + grapes); • System.out.println("address is" + orange); • System.out.println("address is" + banana); • sum=(grapes+orange+banana); • System.out.println(sum); • • • String[] cars = {"Volvo", "BMW", "Ford", "Mazda"}; • System.out.println(cars[0]); • System.out.println(cars[1]); • System.out.println(cars[2]); • System.out.println(cars[3]);
