There are many ways to write a Java String palindrome program. In this Java palindrome example we demonstrate recursion and how the use of loops, arrays, Scanner and the reverse method can improve ...

Java factorial recursion explained Notice how the recursive Java factorial function does not need an iterative loop. Instead, the code repeatedly calls itself until a stop condition is met. In this ...

JDK 7 changes this for Java by introducing the ability to switch on Strings. Specifically, Project Coin delivers on the promise of an ability to switch on Strings.

A recursive approach (which is what I would use) would involve breaking the problem into isomorphic subproblems: to find all permutations of a string, find all permutations of the string without a ...
