一本关于JBuilder 应用开发的书籍,希望大家喜欢,其实我没看过的,

void choice1_itemStateChanged(ItemEvent e) {
    if(choice1.getSelectedItem() == "China"){
      cardLayout1.show(lower,"panel2");
    }
    else if(choice1.getSelectedItem() == "USA"){
      cardLayout1.show(lower,"panel3");
    }
    else if(choice1.getSelectedItem() == "England"){
      cardLayout1.show(lower,"panel4");
    }
    else if(choice1.getSelectedItem() == "Italy"){
      cardLayout1.show(lower,"panel5");
    }
    else if(choice1.getSelectedItem() == "France"){
      cardLayout1.show(lower,"panel6");
    }
  }
