The java.util.Vector.removeAll() method is used to remove from the given vector all of its elements that are contained in the specified collection.
Syntax
public boolean removeAll(Collection<?> c)
Parameters
c |
Specify the collection of elements to be removed from the vector. |
Return Value
Returns true if the vector changed as a result of the call.
Exception
Throws NullPointerException, if the specified collection is null.
Example:
In the example below, the java.util.Vector.removeAll() method is used to remove from the given vector all of its elements that are contained in the specified collection.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//creating a vector
Vector<Integer> vec1 = new Vector<Integer>();
Vector<Integer> vec2 = new Vector<Integer>();
//populating vec1
vec1.add(10);
vec1.add(20);
vec1.add(30);
vec1.add(40);
vec1.add(50);
//populating vec2
vec2.add(20);
vec2.add(40);
vec2.add(60);
//printing vec1
System.out.println("Before removeAll, vec1 contains: " + vec1);
//apply removeAll method on vec1
vec1.removeAll(vec2);
//printing vec1
System.out.println("After removeAll, vec1 contains: " + vec1);
}
}
The output of the above code will be:
Before removeAll, vec1 contains: [10, 20, 30, 40, 50] After removeAll, vec1 contains: [10, 30, 50]
