Bubble sort array

Start learning JAVA 了 , With C At first, it's easy to build the foundation of ,4 I learned a little in August , Later, all kinds of things failed to persist , Forget it, it's . Take your time ！
Just brush to the array , Dare not jump , Afraid to miss something important ！
Bubble sort ！！！

public class arraysort {
    
    public static void main(String[] args) {
    
        int[] arr={
    12,3,43,35,45,656,76,789,987,4543,311};
        int temp=0;
        for(int i=0;i<arr.length-1;i++){
    
            for(int j=0;j<arr.length-i-1;j++){
    
                if(arr[j]>arr[j+1]){
    
                    temp=arr[j+1];
                    arr[j+1]=arr[j];
                    arr[j]=temp;
                }
            }
        }
        for (int i = 0; i < arr.length; i++) {
    
            System.out.print(arr[i]+"\t");
        }
    }
}
