【5】 Java基础 <五> —— 把数组以字符串形式输出

Test1.java

public class Test1 {

    
    static  void  method(int [] a){
        int b ;
        for (int i = 0; i < a.length; i++) {
            
            for (int j = 0; j < a.length-i-1; j++) {
                
                if (a[j]>a[j+1]) {
                    
                    b=a[j+1];
                    a[j+1]=a[j];
                    a[j]=b;
                }
            }
        }
    }
}

Test2.java

import java.util.Arrays;

public class Test2 {

    
    public static void main(String[] args) {
        int  i [] = {5,2,13,4,77,6,412,1};
        //Arrays.sort(a);
        
        
        Test1.method(i);
        //把数组以字符串形式输出
        System.out.println(Arrays.toString(i));
    }
}
