Actually Interface are just like a class where it consists only constants and they
We can extend interface via interfaces
We can implement the interface via classes.
In interface needn’t use the “public” or “abstract” keywords – all methods
declared by an interface are automatically public and abstract by default.
A simple example of interface implement is given below.
[sourcecode=’java’]
public interface testInterface {
//one of the method without method body
void disp(String text);
}[/sourcecode]
For implementing this interface through normal class we follow below step:Read More »Interface Class

    public static void main(String[] args) {
        int binary = 4;
        int  hexadecimal = 43;

        //Convert the integer to binary. Stored in String.
        String bin =  Integer.toBinaryString(binary);
        System.out.println(binary + " as binary: " +  bin);

        //Convert the second integer into hex. Stored in String.
        String hex =  Integer.toHexString(hexadecimal);
        System.out.println(hexadecimal + " as hex:  " + hex);

        //To convert back, parse the String with base 2  (binary).
        System.out.println(bin + " as integer: " + Integer.parseInt(bin,  2));

        //Hexadecimal is base-16, so pass in 16 as base.
        System.out.println(hex +  " as integer: " + Integer.parseInt(hex, 16));
    }

public static void main(String[] args) {

int binary = 4;

int hexadecimal = 43;

//Convert the integer to binary. Stored in String.

String bin = Integer.toBinaryString(binary);

System.out.println(binary + " as binary: " + bin);

//Convert the second integer into hex. Stored in String.

String hex = Integer.toHexString(hexadecimal);

System.out.println(hexadecimal + " as hex: " + hex);

//To convert back, parse the String with base 2 (binary).

System.out.println(bin + " as integer: " + Integer.parseInt(bin, 2));

//Hexadecimal is base-16, so pass in 16 as base.

System.out.println(hex + " as integer: " + Integer.parseInt(hex, 16));

}

Just paste these java codes in your java file .Compile and Run it . Now u will be able to easily convert the Number… Read More »Converting Number System
