设置一个数组，设置一个插入值，这个数组是升序排列确保插入后也是升序Java

package jldx01;

import java.util.Arrays;

public class Demo7 {
public static void main(String[] args) {
int arr [] ={1,2,4,5,49};
int insertNum = 23;
int index =-1;
for (int i = 0; i < arr.length ; i++) {
if(insertNum<=arr[i]){
index = i;
break;
}

    }
    if (index==-1){
        index= arr.length;
    }
    System.out.println("index="+index);
    int [] arrNew = new int[arr.length+1];
    for (int i = 0,j=0; i < arrNew.length ; i++) {
        if (i!=index){
            arrNew[i]= arr[j];
            j++;
        }else {
            arrNew[i]=insertNum;
        }
    }
    arr  = arrNew;
    for (int i = 0; i < arr.length; i++) {
        System.out.println(arr[i]);
    }
}

}
