java - Edit Jframe parent's content from Jframe child -

sorry, have review little project , realize not want transfer data between jframes.

it like

public class jframe2 extends javax.swing.jframe {     public void tryingtodosomething(int i)     {         /*do call setsomething().*/     }  }  public class jframe1 extends javax.swing.jframe {     private int something;     public int setsomething(int something)     {         this.something = something;     }     private jframe2 jframe2 = new jframe2();     public void runthings()     {         jframe2.setvisible(true);     } } 

i have content in first jframe, call second jframe , second jframe, want change content of first jframe (like in example, jframe1 have "int something" , method "setsomething()", called jframe2 , use method "tryingtodosomething(int i)" set value of "int something" of jframe1).

still thank answers.

you should try this:

public class jframe1  extends javax.swing.jframe{   private int something;   public int getsomething()   {      return something;   }   private jframe2 jframe2 = new jframe2();   public void runthings()   {     jframe2.tryingtodosomething();     jframe2.setvisible(true);   } }  

then

public class jframe2 extends jframe1 {  public void tryingtodosomething()    {    /*do call getsomething().*/    getsomething();  } }
