题目是：编写应用程序，用字符界面接受用户10个数字输入，输出这10个整数的最大值和最小值。

程序如下：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class TestOutput {

	public static void main(String[] args) {
		int dataArray [] = new int [10];
		int maxData = 0,minData = 0;
		try{
			InputStreamReader stdin = new InputStreamReader(System.in);
			BufferedReader bufferin = new BufferedReader(stdin);
			for (int i = 0; i < dataArray.length; i++) {
				System.out.print("请输入第"+ (i+1) + "个数：");
				dataArray[i] = Integer.valueOf(bufferin.readLine()).intValue();
			}
			maxData = minData = dataArray[0];
			for (int i = 1; i < dataArray.length; i++) {
				if(maxData < dataArray[i]){
					maxData = dataArray[i];
				}
				if(minData > dataArray[i]){
					minData = dataArray[i];
				}
			}
			System.out.println("最大值是：" + maxData);
			System.out.println("最小值是：" + minData);
		}catch(IOException ioe){
			ioe.printStackTrace();
		}
	}

}
