Type Casting in java?

Type Casting:

Type casting means to explicitly convert one type of data to another type of data. 

Type casting has 2 types:

• Upcasting
• Downcasting

Upcasting:

Converting lower type value to upper type value is known as Upcasting.

Program:

package com.instanceofjavaforus;

public class Upcastingtest {

public static void main(String[] args) {

int a=100;

long b=a;

float c=b;

System.out.println(a);

System.out.println(b);

System.out.println(c);

}

}

Output:

100

100

100.0

Downcasting:

Converting upper type value to lower type value is known as Downcasting.

Program:

package com.instanceofjavaforus;

public class Downcastingtest {

public static void main(String[] args) {

double a=10.4;

long b=(long)a;

int c=(int)b;

System.out.println(a);

System.out.println(b);

System.out.println(c);

}

}

Output:

10.4

Program :

package com.instanceofjavaforus;
class Simple{
public static void main(String args[]){

char ch = 'A';
long a = ch;
System.out.println(a);
}

}

Output:
65

Program:

package com.instanceofjavaforus;
class Simple{
public static void main(String args[]) {
double d = 10.5;
int i = (int) d;
System.out.println(i);
}
}

Output:
10
