Question

How to find the largest (max) element in one dimensional int array in Java

Answer 1

public class Example {
     
    public static void main(String[] args) {
        
        int arr[] = new int[]{2, 234, 48, 17, 98, 918, 800, 12237, 100, 28};
                
        int largetst = arr[0];
                
        for (int i = 1; i < arr.length; i++)
             if (arr[i] > largetst) largetst = arr[i];
                
        System.out.println("Largest element: " + largetst);
    }
}
    


    
/*
run:
 
Largest element: 12237

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Example {
     
    public static void main(String[] args) {
        
        int arr[] = new int[]{2, 234, 48, 17, 98, 918, 800, 12237, 100, 28};
        
        List<Integer> list = new ArrayList<>();
        
        for (int i = 0; i < arr.length; i++) {
            list.add(arr[i]);
        }

        System.out.println("Largest element: " + Collections.max(list));
    }
}
