1.有10个评委打分,(去掉一个最高一个最低)求平均分<br>package yugh; import java.util.*; public class ku { public static void main(String[] args) { Scanner input = new Scanner(System. in ); int [] a = new int [10]; System. out .println( "请输入10位评委的分数:" ); for ( int i = 0; i < 10; i++) { a[i] = input.nextInt(); } int max, min, sum; max = a[0]; min = a[0]; sum = 0; for ( int i = 0; i < 10; i++) { if (max < a[i]) { max = a[i]; } if (min > a[i]) { min = a[i]; } sum = sum + a[i]; } int aver; aver = (sum - max - min) / 8; System. out .println( "去掉最高分和最低分后的平均分是:" + aver); } } |

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。<br>package yugh; import java.util.Random; public class ll { public static void main(String[] args) { Random s= new Random(); int i=s.nextInt(100); Random r= new Random(); for ( int =0;j<10;j++) { int j = r.nextInt(100); System. out .println(j); } } } |

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)<br>package yugh; import java.util.Random; public class oi { public static void main(String[] args) { Random rand = new Random(); int []arr= new int [7]; for ( int i=0;i<7;i++) { arr[i]=rand.nextInt(35)+1; } for ( int i = 0; i < arr.length; i++) { System. out .println(arr[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<br>package yugh; import java.util.Random; public class oy { 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 a=0,b=0; for ( int i=0;i<score.length;i++){ if (score[i]%2==0){ b++; } else { a++; } } 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:" +a); System. out .println( "偶数个数:" +b); } } |
