Answer 1

你是问init2和paint2为什么不执行？applet自己中只会运行init和paint的，不会运行init2和paint2的，你要运行的话必须自己调用
import java.awt.Graphics;
import javax.swing.JApplet;
import javax.swing.JOptionPane;
import java.applet.Applet;
import java.awt.Graphics;public class sss3 extends Applet
{
int number1;
int number2;
int number3;
int number4;
int number5;
int number6;
int number7;
int number8;

public void init()
{
String firstnumber;
String secondnumber;
String thirdnumber;
String forthnumber;

firstnumber=JOptionPane.showInputDialog("input the first number:");
secondnumber=JOptionPane.showInputDialog("input the second number:");
thirdnumber=JOptionPane.showInputDialog("input the third number:");
forthnumber=JOptionPane.showInputDialog("input the forth number:");

number1=Integer.parseInt(firstnumber);
number2=Integer.parseInt(secondnumber);
number3=Integer.parseInt(thirdnumber);
number4=Integer.parseInt(forthnumber);

init2();
}

public void init2()
{
String firstnumber2;
String secondnumber2;
String thirdnumber2;
String forthnumber2; firstnumber2=JOptionPane.showInputDialog("input the first2 number:");
secondnumber2=JOptionPane.showInputDialog("input the second2 number:");
thirdnumber2=JOptionPane.showInputDialog("input the third2 number:");
forthnumber2=JOptionPane.showInputDialog("input the forth2 number:");

number5=Integer.parseInt(firstnumber2);
number6=Integer.parseInt(secondnumber2);
number7=Integer.parseInt(thirdnumber2);
number8=Integer.parseInt(forthnumber2);
}   

public void paint(Graphics g)
{
g.drawRect(number1,number2, number3, number4);

paint2(g);
}
  
public void paint2(Graphics h)
{   
h.drawRect(number5,number6, number7, number8);
}
}
