The Java.util.Stack.remove(Object o) method is used to remove any particular element from the Stack.
Syntax:
Stack.remove(Object o)
Parameters: This method accepts a mandatory parameter o is of the object type of Stack and specifies the element to be removed from the Stack.
Return Value: Returns True if the specified element is found and removed from the Stack, else False.
Below program illustrate the Java.util.Stack.remove(Object o) method:
Example 1:
// Java code to illustrate remove() when position of // element is passed as parameter import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<String> stack = new Stack<String>();
// Use add() method to add elements in the Stack
stack.add( "Geeks" );
stack.add( "for" );
stack.add( "Geeks" );
stack.add( "10" );
stack.add( "20" );
// Output the Stack
System.out.println( "Stack: " + stack);
// Remove the element using remove()
boolean res = stack.remove( "20" );
// Print the removed element
System.out.println( "Was 20 removed: "
+ res);
// Print the final Stack
System.out.println( "Final Stack: "
+ stack);
}
} |
Output:
Stack: [Geeks, for, Geeks, 10, 20] Was 20 removed: true Final Stack: [Geeks, for, Geeks, 10]
Example 2:
// Java code to illustrate remove() when position of // element is passed as parameter import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<Integer> stack = new Stack<Integer>();
// Use add() method to add elements in the Stack
stack.add( 10 );
stack.add( 20 );
stack.add( 30 );
stack.add( 40 );
stack.add( 50 );
// Output the Stack
System.out.println( "Stack: " + stack);
// Remove the element using remove()
boolean res = stack.remove( "100" );
// Print the removed element
System.out.println( "Was 100 removed: "
+ res);
// Print the final Stack
System.out.println( "Final Stack: "
+ stack);
}
} |
Output:
Stack: [10, 20, 30, 40, 50] Was 100 removed: false Final Stack: [10, 20, 30, 40, 50]
