JAVA语法——冒泡排序

有地方写错了。所以一直都没办法运行

 

package 冒泡排序;

public class 冒泡排序 {
    public static void main(String[] args)
    {
        int[] arr = {6,3,8,2,9,1};
        
        System.out.println("排序前数组为：");
        
        for(int num:arr)
            System.out.print(num+" ");
        
        //核心代码
        for(int i = 0; i <= arr.length-1; i++)
            for(int j = 0; j <= arr.length-1-i; j++)
                if(arr[j] > arr[j+1])
                {
                    int temp = arr[j];
                    arr[j] = arr[j+1];
                    arr[j+1] = temp;
                }
        
        System.out.println();
        System.out.println("排序后的数组为");
        
        for(int num:arr)
            System.out.print(num+" ");
    }
}
