求数组里最大值

 

import java.util.Scanner;
public class For02{
    public static void main(String[] args){
    
    //Scanner myScanner = new Scanner(System.in);
    System.out.println("求最大值,和最大值的下标");
    
    //int num = myScanner.nextInt();
    int [] arr = {4,-1,9,10,23};
    
    int max=arr[0];
    int maxIndex=0;
    
        for(int i=0;i<arr.length;i++){
            if(arr[i]>max){
            max=arr[i];//将大的值放到max
            maxIndex=i;
        }//结束if
        }//结束for循环
    System.out.println("max:"+max);
    System.out.println("maxIndex:"+maxIndex);
    
}//结束主方法                                          
}//结束程序
