Answer 1

Modify your class, add data members to place your labels there, add a modify method with parameters will be better. Additionally, ths setText is a method with String parameter that will be used to change the label's text. So it'll be something like this

public class lang {
    private jLabel lbl1;
    private jLabel lbl2;
    public lang(jLabel lbl1, jLabel lbl2){
        this.lbl1 = lbl1;
        this.lbl2 = lbl2;
    }

    public void urdu(){
        lbl1.setText("udru1");    
        lbl2.setText("udru2");       
    }
    //modify method
    public void modify(String txtLabel1, String txtLabel2){
        lbl1.setText(txtLabel1);
        lbl2.setText(txtLabel2);
    }
 }
