package com.ie;

import java.io.IOException;

public class Add {

private int firstNumber;

private int secondNumber;

public static void main(String args[]){
Add add = new Add();
System.out.println("请输入第一个数据:");
add.setFirstNumber(add.input());
System.out.println("请输入第二个数据:");
add.setSecondNumber(add.input());
System.out.println("求和结果为:\n"+add.sum());
}

//输入数据
public int input(){
int date = 0;
try {
for(;;){
byte temp[] = new byte[20];
System.in.read(temp);
if(this.isOK(Integer.parseInt(new String(temp).trim()))){
date = Integer.parseInt(new String(temp).trim());
break;
}else{
System.out.println("输入的数据要求在0-100之间，重新输入！！！");
}
}
} catch (IOException e) {
e.printStackTrace();
}
return date;
}

//判断输入的数据是否在指定的范围内
public boolean isOK(int date){
if(date>=0&&date<=100){
return true;
}else{
return false;
}
}

//完成求和功能
public int sum(){
int start = 0;
int end = 0;
int sum = 0;
if(this.getFirstNumber()<=this.getSecondNumber()){
start = this.getFirstNumber();
end = this.getSecondNumber();
}else{
start = this.getSecondNumber();
end = this.getFirstNumber();
}
for(int temp = start; temp <= end; temp++){
sum = sum + temp;
}
return sum;
}

public int getFirstNumber() {
return firstNumber;
}

public void setFirstNumber(int firstNumber) {
this.firstNumber = firstNumber;
}

public int getSecondNumber() {
return secondNumber;
}

public void setSecondNumber(int secondNumber) {
this.secondNumber = secondNumber;
}

}

嗯好像不对啊，跟题目要求的有点儿差别
