Java - Add Parameter to Class -

i trying add parameter @ declaration of class.

here declaration:

public static class tcp_ping implements runnable {      public void run() {     }  } 

this trying do:

public static class tcp_ping(int a, string b) implements runnable {      public void run() {     }  } 

(which doesn't work)

any suggestions? thanks!

you want declare fields, , values of parameters in constructor, , save parameters fields:

public static class tcp_ping implements runnable {   // these fields:   private final int a;   private final string b;    // constructor, takes parameters   public tcp_ping(final int a, final string b) {     // here save parameters fields     this.a = a;     this.b = b;   }    // , here (or in other method create) can use fields:   @override public void run() {     system.out.println("a: " + a);     system.out.println("b: " + b);   } } 

then can create instance of class this:

tcp_ping ping = new tcp_ping(5, "www.google.com");
