1.有10个评委打分,(去掉一个最高一个最低)求平均分。
package chap1;
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{
int[] score = new int[10];
Scanner s = new Scanner(System.in);
System.out.println("请输入10位评委的分数");
for (int i = 0; i < score.length; i++)
{
score[i] = s.nextInt();
}
for (int i = 0; i < score.length - 1; i++)
{
for (int j =0; j < score.length - 1 - i; j++)
{
if (score[j] > score[j + 1])
{
int tmp = score[j];
score[j] = score[j + 1];
score[j + 1] = tmp;
}
}
}
int sum = 0;
for (int i = 1; i < score.length - 1; i++)
{
sum += score[i];
}
System.out.println("平均分为:" + sum / (score.length - 2.0));
}
}
2.自学一下Java随机数，生成一个长度为10的随机数组（每个数的范围是0~99），排序后输出。
package chap1;
import java.util.Random;
public class Main
{
public static void main(String[] args)
{
int[] score = new int[10];
Random r = new Random();
for (int i = 0; i < score.length; i++)
{
score[i] = r.nextInt(100);
}
for (int i = 0; i < score.length - 1; i++)
{
for (int j =0; j < score.length - 1 - i; j++)
{
if (score[j] > score[j + 1])
{
int tmp = score[j];
score[j] = score[j + 1];
score[j + 1] = tmp;
}
}
}
for (int i = 0; i < score.length; i++)
{
System.out.println(score[i]);
}
}
}
3.制作彩票35选7程序。 （就是1~35随机生成7个不重复的数）
package chap1;
import java.util.Random;
public class Main
{
public static void main(String[] args)
{
int[] score = new int[7];
Random r = new Random();
for (int i = 0; i < score.length; i++)
{
score[i] = r.nextInt(35) + 1;
}
System.out.println("35选7号码为:");
for (int i = 0; i < score.length; i++)
{
System.out.println(score[i]);
}
}
}
4.定义一个长度为10的int数组(如果没有特殊说明,静态赋值动态赋值都可以),统计数组中的最大值、最小值、以及奇 数和偶数的个数
package chap1;
import java.util.Random;
public class Main
{
public static void main(String[] args)
{
int[] score = new int[10];
Random r = new Random();
for (int i = 0; i < score.length; i++)
{
score[i] = r.nextInt(100);
}
System.out.println("原数组为:");
for (int i = 0; i < score.length; i++)
{
System.out.println(score[i]);
}
for (int i = 0; i < score.length - 1; i++)
{
for (int j =0; j < score.length - 1 - i; j++)
{
if (score[j] > score[j + 1])
{
int tmp = score[j];
score[j] = score[j + 1];
score[j + 1] = tmp;
}
}
}
int ji = 0, ou = 0;
for (int i = 0; i < score.length; i++)
{
if (score[i] % 2 == 0)
{
ou++;
}
else
{
ji++;
}
}
System.out.println("最小值为:" + score[0]);
System.out.println("最大值为:" + score[score.length - 1]);
System.out.println("奇数个数:" + ji);
System.out.println("偶数个数:" + ou);
}
}
