Using Primitive Data Types

Demo Code

public class Main {  
  public static void main(String[] args) {
    int anInt = 1;
    long aLong = 22200L;
    byte aByte = 65;
    short aShort = -02;
    char aChar = 'A';
    float aFloat = 1111.98F;
    double aDouble = 999.89;
    /*from  www  .j  av  a 2 s .com*/
    // Print values of the variables
    System.out.println("anInt = " + anInt);
    System.out.println("aLong = " + aLong);
    System.out.println("aByte = " + aByte);
    System.out.println("aShort = " + aShort);
    System.out.println("aChar = " + aChar);
    System.out.println("aFloat = " + aFloat);
    System.out.println("aDouble = " + aDouble);
    System.out.println("aDouble = " + aDouble);
    
    // Print sone double constants
    System.out.println("Max double = " + Double.MAX_VALUE);
    System.out.println("Min double = " + Double.MIN_VALUE);
    System.out.println("Positive infinity for double = " + Double.POSITIVE_INFINITY);
    System.out.println("Negative infinity for double = " + Double.NEGATIVE_INFINITY);
    System.out.println("Not-a-Number for double = " + Double.NaN);
    System.out.println("double takes " + Double.BYTES + " bytes");
  }
