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
