java程序编写：键盘输入十个数，输出最大数。麻烦把每一步都是什么意思写在后面 纯新手 用JAVA编写一个简单的计算器，要求如下

Scanner scanner = new Scanner(System.in);///创建Scanner对象 接受从控制台输入
System.out.println("请输入所需整数的个数！");

int[] b = new int[a];//建一个数组来存数字
for(int i=0;i<a;i++){
System.out.println("请输入第"+(i+1)+"个整数！");
b[i]=scanner.nextInt();////接受int型的一个数字，并把它存入数组
}
//先把你输入的数字都打印一下，用于比较
System.out.println("你所需要比较的数字为：");
for(int i=0;i<a;i++){

//这里开始比较大小了
int min = b[0];
int max = b[0];

if(max<b[i])
max=b[i];
}

}

这个方法行吗？
import java.util.Collections;
import java.util.Scanner;
import java.util.Vector;

//测试类
public class Test {
@SuppressWarnings("unchecked")
public static void main(String[] args){
//创建一个获取键盘输入数据的对象；
Scanner scanner = new Scanner(System.in);
//创建一个数组
Vector vector = new Vector();
System.out.println("请输入十个数：");
//为数组添加十个数
for(int i = 0; i < 10; i++)
vector.add(scanner.nextInt());
//使用超类中的Collections的sort方法对数组进行排序；
Collections.sort(vector);
//打印输出最后一个元素的值。
System.out.println(vector.lastElement());
}
}

#include<stdio.h>
#include <stdlib.h>
void main(){
int a[10],i,j,t;//声明需要用到的变量
printf("输入10个数字\n");
for(i=1;i<10;i++)//for循环接受收入的10个数据
scanf("%d",&a[i]);
printf("\n");
for(i=1;i<=8;i++)//从第一个数循环到第8个数
for(j=1;j<=9-i;j++)//从内层循环
if(a[j]>a[j+1]){//开始比较 如果前面的一个数大于后面一个数 就让它们交换数组位置
t=a[j];
a[j]=a[j+1];
a[j+1]=t;
}
printf("排序后数字是\n");
for(i=1;i<10;i++)//打印
printf("排序好的数字是%d\n",a[i]);
system("pause");
}

推荐冒泡排序法去比较，具体的你先看，如果实在不行的话，我在帮你写代码，学习编程最重要的是自己多动脑子，多动手，希望你技术越来越好！
