number3.java

实验目的：让学生掌握开发Java应用程序的三个步骤：编写源文件、编译源文件和运行应用程序。掌握Java程序的基本语句。 1、试编写一个程序

import javax.swing.JOptionPane;

public class Number3{
	public static void main(String[] args){
		String output = "";
		double incressNumber=1.075;
		int year = 0;
		while(true){
			if (incressNumber >= 4){
				break;
			}
			incressNumber *= 1.075;
			year ++;
		}
		output += year + " years later the XXX will incress 4 times!";
		JOptionPane.showMessageDialog(null,output,"Example 3 Output",JOptionPane.INFORMATION_MESSAGE);
	}
}
