how can i define only one method from the interface.

Hi friend,

If u declare the methods in interface then it must be define in the class
that implement the interface.

for e.g :

interface abc
{
public void m1();
public void m2();
public void m3();
}
class c1 implements abc
{
public void m1()
{
System.out.println("Hello world");
}
public void m2()
{
System.out.println("Hello world");
}

public void m3()
{
System.out.println("Hello world");
}

}


Thanks
