Java Examples - Vector Maximum

Problem Description

How to get the maximum element from a vector ?

Solution

Following example demonstrates how to get the maximum element of a vector by using v.add() method of Vector class and Collections.max() method of Collection class.

import java.util.Collections;
import java.util.Vector;

public class Main {
   public static void main(String[] args) {
      Vector<Double> v = new Vector<Double>();
      v.add(new Double("3.4324"));
      v.add(new Double("3.3532"));
      v.add(new Double("3.342"));
      v.add(new Double("3.349"));
      v.add(new Double("2.3"));
      Object obj = Collections.max(v);
      System.out.println("The max element is:"+obj);
   }
}

Result

The above code sample will produce the following result.

The max element is: 3.4324

The following is an another example to get the maximum element of a vector by using v.add() method of Vector class and Collections.max() method of Collection class.

import java.util.Vector;
import java.util.Collections;
 
public class Demo {
   public static void main(String[] args) {
      Vector vec = new Vector();
      vec.add(new Double("24.42"));
      vec.add(new Double("45.32"));
      vec.add(new Double("42.42"));
      vec.add(new Double("57.39"));
      vec.add(new Double("23.34"));
      Object object1 = Collections.max(vec);
      System.out.println("Maximum Element is : " + object1);
   }
}

Result

The above code sample will produce the following result.

Maximum Element is : 57.39
