作业习题

实验代码：

import java.util.Scanner;class chazhao {public static void main(String[] args) {Scanner sc=new Scanner(System.in);System.out.println("请输入你要的数组");String line= sc.nextLine();String[] lineArr=line.split(" ");int[] list=new int[lineArr.length];for (int i = 0; i < list.length ; i++) {list[i]=Integer.parseInt(lineArr[i]);}for (int i = 0; i < list.length-3 ; i++) {if(list[i]==list[i+1]&&list[i+1]==list[i+2]&&list[i+2]==list[i+3]){System.out.println("true");break;}else {System.out.println("false");}}}}

运行结果如图所示：

第二题代码：

import java.util.Arrays;
import java.util.Scanner;class Code_31 {public static void main(String[] args) {Scanner input=new Scanner(System.in);System.out.print("Enter list1 size and contents:");int length1=input.nextInt();int[] list1=new int[length1];for(int i=0;i<list1.length;i++){list1[i]=input.nextInt();}System.out.print("Enter list2 size and contents:");int length2=input.nextInt();int[] list2=new int[length2];for(int i=0;i<list2.length;i++){list2[i]=input.nextInt();}for(int i=0;i<merge(list1,list2).length;i++)System.out.print(merge(list1,list2)[i]+" ");}public static int[] merge(int[] list1,int[] list2){int[] list3=new int[list1.length+list2.length];for(int i=0;i<list1.length;i++){list3[i]=list1[i];}for(int i=list1.length,j=0;i<list1.length+list2.length;i++,j++){if(j>list2.length)break;list3[i]=list2[j];}Arrays.sort(list3);return list3;}
}

运行结果:
