最大值,最小值

package hello;

public class Zuidazhi {

    public static void main(String[] args) {
        int[] a =new int[]{1,2,3,4,5,6};
        int b=a[0];
        System.out.println(a[0]);
        for(int j=0;j<a.length;j++){
            if(b<a[j])
            {
            b=a[j];
            }
            }
            System.out.println("最大数是："+b);

    }

}
 

最小值:

package hello;

public class zuixiaozhi {

    public static void main(String[] args) {
        int []a=new int[]{1,2,3,4,5,6};
        int b=a[0];
        for(int i=0;i<a.length;i++){
            if(b>a[i]){
            
            b=a[i];}
            
            }
        System.out.println(b);
        
        }
    }
