Java Type Casting

Syntax:-

 (type)value;

Implicit conversion:

It does not require any operator for converted. They are automatically performed when a value is copied to a consistent type in the program.

The value has been promoted from int to double and we have not to specify any type-casting operator. This is known as standard conversion.

Example:-

public class Implicitcasting
{  
	public static void main(String[] args) {   
        int i=20;
		double p;
		p=i;     
		System.out.println("Implicit value is "+p);          
    }    
} 

Explicit conversion:

Many conversions that involve a different interpretation of the value require an explicit conversion.

They are not automatically performed. It need to give explicit type casting in the program.

Example:-

public class Explicitcasting
{  
	public static void main(String[] args) {   
        int i=9, j=2;
        double z;
        z = (double) i / j;  
    	System.out.println("Value of Z : "+z);          
    }    
}

If the float is converted to int, data which is present after the decimal point will be lost.
