数组的排序(sort和冒泡)

1.sort排序

public class Test {
    public static void main(String[] args) {
        
        int[] a = {1,6,9,3,2,8};
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i]);
            
        }
        System.out.println();
        Arrays.sort(a);
    
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i]);
            
        }
    }
}

2.冒泡排序法

public class Test {
    public static void main(String[] args) {
        
        int[] a = {1,6,9,3,2,8};
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i]);
            
        }
        System.out.println();
        for (int i = 0; i < a.length; i++) {
            for (int j = 0; j < a.length-1; j++) {
                
                if (a[j]>a[j+1]) {
                int    temp=a[j];
                a[j]=a[j+1];
                a[j+1]=temp;
                
                }
            }
            
        }
    
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i]);
            
        }
    }
}
