Basic Data Types in Java Programming – Example Code

In previous post we learned how to write a very simple hello world Java program. In this simple program we will explain what are some different data types in Java. We use specific data types to define variable depending upon the nature of data we want to store in variable.

public class DataTypesJava {

   public static void main(String[] args) {
      //single line comment

      boolean isBoolean = true; // boolean data type store either true or false
      int isInt = 120; // int data type is used to store integer values
      int mult = isInt * 2; // multiplication is basic arithmetic operation
      int mod = isInt % 2; // modulus operator is used to find remainder
      System.out.println('A'); //characters are enclosed in single quotes
      System.out.println("Some String Text"); // strings are enclosed in double quotes
      System.out.println(isInt / 2); // division is simple arithmetic operation

    1. Its the output of ‘mod’ variable (modulus operator). When we divide 120 by 2 then the modulus (remainder is 0). That’s why its output is 0.
