java开发小程序代码 小程序开发代码大全
用java写一个小程序
java实现先输入10个int类型的参数，之后循环判断找到最大值和最小值，保存起来和其他的值进行比较。代码如下：

public class Test{
public static void main(String args[]){
int i,min,max;
int A[] = new int[10];
Scanner input=new Scanner(System.in);
for(int j=0,j10;j++){//输入10个数
System.out.println("请输入一个数字：");
int length=input.nextInt();//输入一个数字
A[i] =length;
}
min=max=A[0];
System.out.print("数组A的元素包括：");
int j =0;
int n =0 ;
for(i=0;iA.length;i++)
{
System.out.print(A[i]+" ");
if(A[i]max) // 判断最大值
j =i;
max=A[i];
if(A[i]min) // 判断最小值
min=A[i];
n =i
}
System.out.println("\n数组的最大值是："+max+".数组的位置是："+（j+1）); // 输出最大值和最大值的位置
System.out.println("数组的最小值是："+min+".数组的位置是："+（n+1）); // 输出最小值
}
}
用java编一个小程序
import java.io.*;
public class BaiduJava
{
public static int[] input(String arg)
{
int n=Integer.parseInt(arg);
int i=0;
int a[]=new int[n];
while(in)
{
System.out.print("input "+(i+1)+" number :");
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
try
{
a[i]=Integer.parseInt(br.readLine());
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
i++;
}
return a;
}
public static int[] sort(int[] a)
{
for(int i=0;ia.length-1;i++)
{
for(int j=i+1;ja.length;j++)
{
int t;
if(a[i]a[j])
{
t=a[i];
a[i]=a[j];
a[j]=t;
}
}
}
return a;
}
public static void main(String[] args)
{
int[] b=sort(input(args[0]));
for(int i=0;ib.length;i++)
System.out.print(b[i]+" ");
System.out.println();
}
}
运行过了，没问题。命令行第一个参数输入n
