Java Programming 1: LAB 4
Note: You have to show the answers to the tutor during the lab hours. The tutor will assess anyour answers d mark will be awarded to those students who finish this exercise.
Objectives:
• To be able to display message/ get input by using JOptionPane class
• To be able to use arithmetic operators.
• To understand the precedence of arithmetic operators.
Question 1:
// Example which display text using dialog box
import javax.swing.JOptionPane;
class LabExerciseGUI
{
public static void main(String[ ] args)
{
JOptionPane.showMessageDialog(null,
"Jennifer \n 1000123456 \n 1980 \n\n Good Luck");
System.exit(0);
} // end main
} // end class
Program 1
Copy the above LabExerciseGUI class. Modify the it with your own name, your ID number, Date of

抱歉，只能用C++来解决你的第二个问题，
#include <iostream>
using namespace std;
int main(){
int a,b,c,sum,multiplication,average;
cout<<"Input a:";
cin>>a;
cout<<"Input b:";
cin>>b;
cout<<"Input c:";
cin>>c;
sum=a+b+c;
multiplication=a*b*c;
average=sum/3;
cout<<"The sum is "<<sum
<<",the multiplication is "
<<multiplication<<endl;
<<"and the average is "<<average;
return 0;
}
上面的代码没有经过调试，你可以试一下，
我不会JAVA，但是C++和JAVA很像，相信你有能力将其
转换成JAVA代码。
另外，你说的那个screen shot in page 2. 并没有给出，因此我没有办法做到像你所说第二页中的那个截图完全相同。还是很抱歉其他两题我也不会。。
