JAVA基础学习之路（六）数组与方法参数的传递

public class test2 {
    public static void main(String args[]) {
        int arr[] = new int[] {9, 1, 2, 3, 4, 7, 8, 6, 5 };
        sort(arr);
        for(int i=0; i<arr.length; i++) {
            System.out.println(arr[i]);
        }
    }
    
    public static void sort(int arr[]) {//冒泡排序
        for (int x= 0; x<arr.length; x++) {
            for (int y=0; y<arr.length-1; y++) {
                if (arr[y] > arr[y+1]) {
                    int  temp;
                    temp = arr[y];
                    arr[y] = arr[y+1];
                    arr[y+1] = temp;    
                }
            }
            
        }
    }
        
}
