      for(int j=0;j<n-i-1;j++){
        if(arr[j]>arr[j+1]){
            int temp=arr[j];
            arr[j]=arr[j+1];
            arr[j+1]=temp;

}

Answer 1

据我所知，这应该有效

import java.util.Arrays;

public class Program
{
   public static void main(String[] args ) {
      int[] arr={3,5,7,2,1,8};
      int n=arr.length;
     for(int i=0;i<n-1;i++){
      for(int j=0;j<n-i-1;j++){
        if(arr[j]>arr[j+1]){
            int temp=arr[j];
            arr[j]=arr[j+1];
            arr[j+1]=temp;
        }  
      }
    }
       System.out.print ( Arrays.toString(arr) );  
  }
}
