In java Interface provides the definition of methods and
final variables. The variables can be declared as final or
not but its can not be changed or modified again. valiable
value can be decide only at the time of declaration.

for more clearance please go through the example given below.

// declaring an interface
public interface MyInterface {

public static final int y = 9;

public void service();
public int method();
public abstract void newmethod();

}

// implementing an interface by a class
public class Class1 implements MyInterface{

/**
* @param args
*/
public Class1(){
System.out.println(y);

}
public void service(){};
int i =9;


public int method(){
final int q = 10;

return q;
}

public void newmethod(){
System.out.println("Tarun");
}

public static void main(String[] args) {
// TODO Auto-generated method stub
Class1 c1 = new Class1();
}

}
