Java Vector forEach() Method

The forEach() method of Java Vector class is used to perform the given action for each element of the Iterable until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration if that order is specified.

Syntax:

Following is the declaration of forEach() method:

Parameter:

Parameter	Description	Required/Optional
action	It is an action which will be performed for each element.	Required

Returns:

The forEach() method does not return anything. It only performs the given action for each element.

Exceptions:

NullPointerException- This method has thrown an exception if the specified action is null.

Compatibility Version:

Java 1.2 and above

Example 1:

import java.util.*;
public class VectorForEachExample1 {  
	public static void main(String arg[]) {	
	    //Create an empty vector
	    Vector<Integer> vec = new Vector<>();
	    //Add element in the vector
	    vec.add(1);
	    vec.add(2);
	    vec.add(3);	    
	    vec.add(4);
	    vec.add(5);  
	    //Use forEach() method to print vector elements
	    vec.forEach(System.out::println);
	    }            
}

	    Vector < String > colors = new Vector < String > ();
	    //Add elements in the vector
          colors.add("White");
          colors.add("Green");
          colors.add("Black");
          colors.add("Pink");
