Java program to reverse a string using stacks - In this article, we will understand how to reverse a string using stacks. String is a datatype that contains one or more characters and is enclosed in double quotes(“”). The stack is a linear data struct
At the end of the loop the variable reversenum contains the reverse number and the program prints the value of this variable as output. importjava.util.Scanner;classReverseNumberWhile{publicstaticvoidmain(Stringargs[]){intnum=0;intreversenum=0;System.out.println("Input your number and press en...
