Java Program - 03 - Type Casting

Java Program - 03

Write a java program to show the concept of type conversion.

 

 

public class StudyViral_03 {

 public static void main(String[] args) {

  int a = 127;
  a = a + 1;
  System.out.println("New Value of A = "+a);
  
  byte b = 127;
  b = b + 1;//Error explicit required
  System.out.println("New Value of B = "+b);
  
  int c = 100;
  c = c + 1.0;//Error explicit required
  
  System.out.println("New Value of C :: "+c);
  
  double d = c + 1.0;
  System.out.println("New Value of D :: "+d);
 }
}

============================================================== 

//Correct Program 

public class StudyViral_03 {

 public static void main(String[] args) {

  int a = 127;
  a = a + 1;
  System.out.println("New Value of A = "+a);
  
  byte b = 127;
  b = (byte) (b + 1);//Explicit casting (Forcefully Convert int to byte) 

                     //because 1 is int and variable b is of type byte
  System.out.println("New Value of B = "+b);
  
  int c = 100;
  c = (int) (c + 1.0);//Explicit casting (Forcefully Convert 1.0 double to int)

                      //1.0 is double and variable c is of type int
  
  System.out.println("New Value of C :: "+c);
  
  double d = c + 1.0;//Implicit Type Casting done 

                     //Convert from lower to higher Data Type
  System.out.println("New Value of D :: "+d);
 }
}

 Output ::

New Value of A = 128
New Value of B = -128
New Value of C :: 101
New Value of D :: 102.0

//Java Program to show the use of simple/premitive data types.

class StudyViral_02{

    public static void main(String []args){
        byte byteCar = 100;
        short shortVar = 123;
        int intVar = 123456;
        int calcVar = -98765432;
        long longVar = 1234567891L;
        float floatVar = 12.356F;
        double doubleVar =  123456.6666d;
        boolean flag = true;
        boolean val = false;
        char ch1 = 89;
        char ch2 = 'Z';

        System.out.println("byte value = "+byteCar);
        System.out.println("short Value = "+shortVar);
        System.out.println("int Value = "+intVar);
        System.out.println("long Value = "+longVar);
        System.out.println("float Value = "+floatVar);
        System.out.println("double Value = "+doubleVar);
        System.out.println("boolean Value = "+flag);
        System.out.println("boolean Value ="+val);
        System.out.println("char ch1 = "+ch1);
        System.out.println("char ch2 = "+ch2);

    }

}

Output:: 

byte value = 100
short Value = 123
int Value = 123456
long Value = 1234567891
float Value = 12.356
double Value = 123456.6666
