编写程序实现如下界面效果：

import java.util.Scanner;public class Test01 {public static void main(String[] args) {String name;Scanner input = new Scanner(System.in);System.out.println("请输入您的姓名：");name = input.nextLine();System.out.println(name+"，您好！欢迎学习Java。");}}

编写字符界面版计算器程序，运行时提示输入两个操作数，然后输出加减乘除运行结果。

import java.util.Scanner;
public class Test02 {public static void main(String[] args) {double number1,number2;System.out.println("=======字符版计算器=======");Scanner input = new Scanner(System.in);System.out.print("请输入第一个操作数：x=");number1 = input.nextDouble();System.out.print("请输入第二个操作数：y=");number2 = input.nextDouble();System.out.println("运算结果如下：");System.out.println("x+y="+(number1+number2));System.out.println("x-y="+(number1-number2));System.out.println("x*y="+(number1*number2));if(number2 != 0){System.out.println("x/y="+(number1/number2));}else {System.out.println("除数为0，运算无意义。");}}}

 

修改第（2）题程序，使得程序输出的运算结果中，能直接显示所输入的数据，而不是x+y之类。

import java.util.Scanner;
public class Test02 {public static void main(String[] args) {double number1,number2;System.out.println("=======字符版计算器=======");Scanner input = new Scanner(System.in);System.out.print("请输入第一个操作数：x=");number1 = input.nextDouble();System.out.print("请输入第二个操作数：y=");number2 = input.nextDouble();System.out.println("运算结果如下：");System.out.println(number1+"+"+number2+"="+(number1+number2));System.out.println(number1+"-"+number2+"="+(number1-number2));System.out.println(number1+"*"+number2+"="+(number1*number2));if(number2 != 0){System.out.println(number1+"/"+number2+"="+(number1/number2));}else {System.out.println("除数为0，运算无意义。");}}}
