If there are no syntax errors in your code, the Java compiler (javac) will create a file named PrintDataTypes.class
in the same directory.
Step 3: Running the Java Program

1 Run the Java Program:

In the Command Prompt, type the command java filename (java PrintDataTypes) and press Enter:
This command executes the main method in the PrintDataTypes class. You should see the values of the variables
printed in the console.
Summary
This Java program declares variables of different primitive data types and prints their values to the console.
Following the steps outlined above will allow you to create and run the program successfully.

TASK 2 : Write a Java program to display all primitive data types
All the steps are same as that of the above program (See the steps of Task 1)
CODE:
public class PrimitiveExample {
public static void main(String[] args) {

// Declare variables of different primitive data types
byte myByte = 10;
short myShort = 1000;
int myInt = 100000;

long myLong = 1000000000L;
float myFloat = 3.14f;
double myDouble = 3.14159;
boolean myBoolean = true;
char myChar = ‘A’;

// Print the values of the variables
System.out.println(“byte: “ + myByte);
System.out.println(“short: “ + myShort);
System.out.println(“int: “ + myInt);
System.out.println(“long: “ + myLong);

System.out.println(“float: “ + myFloat);
System.out.println(“double: “ + myDouble);
System.out.println(“boolean: “ + myBoolean);
