如何在java中跳过/不运行代码

Question

bSub.addActionListener(new ActionListener(){
           public void actionPerformed(ActionEvent e){
               if(t1.getText().equals("Name") || t2.getText().equals("Section") || t3.getText().equals("Age")){
                   JOptionPane.showMessageDialog(null, "Please fill in the incomplete fields");
                }
                //If the 'if statement' above is true, these code below will not execute
               t8.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t9.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t10.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t11.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t12.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
            }
        });

如果'If Statement'为真,是否可以告诉编译器跳过代码？

Answer 1

将其他代码放在else:

public void actionPerformed(ActionEvent e){
           if(t1.getText().equals("Name") || t2.getText().equals("Section") || t3.getText().equals("Age")){
               JOptionPane.showMessageDialog(null, "Please fill in the incomplete fields");
            } else {
              //If the 'if statement' above is true, these code below will not execute
               t8.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t9.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t10.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t11.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
               t12.setText(t1.getText() + " of " + t2.getText() + " -- " + t3.getText() + " years old");
           }

        }
