Java Stack - setSize() Method
The java.util.Stack.setSize() method is used to set the size of the stack. If the new size is greater than the current size, new null items are added to the top of the stack. If the new size is less than the current size, all components at index newSize and greater are discarded.
Syntax
public void setSize(int newSize)
Parameters
newSize |
Specify new size of the stack. |
Return Value
void type.
Exception
Throws ArrayIndexOutOfBoundsException, if the new size is negative.
Example:
In the example below, the java.util.Stack.setSize() method is used to set the size of the stack called MyStack.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//creating a stack
Stack<Integer> MyStack = new Stack<Integer>();
//populating stack
MyStack.push(10);
MyStack.push(20);
MyStack.push(30);
MyStack.push(40);
MyStack.push(50);
System.out.println("MyStack contains: " + MyStack);
MyStack.setSize(3);
System.out.println("MyStack contains: " + MyStack);
MyStack.setSize(5);
System.out.println("MyStack contains: " + MyStack);
}
}
The output of the above code will be:
MyStack contains: [10, 20, 30, 40, 50] MyStack contains: [10, 20, 30] MyStack contains: [10, 20, 30, null, null]
