Given List Integers Find Max value Java Example

Question: Given the list of integers you have to find maximum value from it. Then input parameter will be Java List:

• MaxValueOfIntFromList.java:

package com.intarrayindex;

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

public class MaxValueOfIntFromList {

	public static void main(String[] args) {
		
		List<Integer> values = new ArrayList<>();
		values.add(89);
		values.add(102);
		values.add(48);
		values.add(50);
		
		//Using collections API
		System.out.println("Maximum value from list of int using Collections API: "+Collections.max(values));
		//Using own logic
		System.out.println("Maximum value from list of int using own logic: "+getMaximumValue(values));
		
	}
	
	public static Integer getMaximumValue(List<Integer> values){
	    
		int maxValue = Integer.MIN_VALUE;
	    
	    for(int i=0; i<values.size(); i++){
	        
	    	if(values.get(i) > maxValue){
	            maxValue = values.get(i);
	        }
	    }
	    
	    return maxValue;
	}

}
