已知有个排序好（升序）的数组，要求插入一个元素，最后打印该数组，顺序依然是升序 【10， 12， 45， 90】 23 【10， 12，23， 45， 90】。
public class Test{ public static void main(String[] args) { int addNum = 23; int[] arr = {10,12,45,90}; int[] arr1 = new int [arr.length + 1]; for (int i=0;i<arr.length;i++ ){ arr1 [i] = arr [i]; System.out.print(arr1[i]+"\t"); } arr1 [arr.length ] = addNum; System.out.println(arr1[arr.length ]); int temp = 0; for (int k=0 ;k<arr1.length-1 ;k++ ) { for (int j=0;j< arr1.length-1-k ;j++ ){ if ( arr1 [j] > arr1 [j+1] ){ temp = arr1 [j]; arr1 [j] = arr1 [j+1]; arr1 [j+1] = temp; } } for( int z = 0; z < arr1.length; z++) { System.out.print(arr1 [z] + "\t"); } System.out.println("进行第"+(k+1)+"轮排序"); } } }
