The Stack
class is a Last-In-First-Out (LIFO) stack of objects.
The toString()
method will return the String
representation of the Stack
object. It also returns the String
representation of each element in the stack
.
The syntax of the toString
method is given below:
public String toString()
This method doesn’t take any argument.
This method returns a String
as a result. The returned String
contains the elements of the stack
in the insertion order enclosed between the brackets []
and separated by commas (,)
. Internally, the elements are converted to string using the String.valueOf(Object)
method.
import java.util.Stack;
class ToString {
public static void main( String args[] ) {
Stack<Integer> stack = new Stack<>();
stack.push(1);
stack.push(2);
stack.push(3);
System.out.println(stack.toString());
}
}
In the code above,
Stack
class.Stack
object with the name stack
.1,2,3
) to the stack
object using the push
method.toString
method to get the string representation of the stack
