One of the common Java coding interview questions is towrite a program to reverse a String in place in Java, without using additional memory. You cannot use any library classes or methods likeStringBuilderto solve this problem. This restriction is placed becauseStringBuilderandStringBufferclass define...

In this guide for the day before your coding interview, we have explored some problems and demonstrated the thought process to solve it starting from the brute force solutions. In the process, we have covered all fundamental ideas along with applying Dynamic Programming to String algorithms...
In the following example, the Java String substring method that takes two parameters has been implemented: String id =newString ("xyz@company.com");intstartindex = id.indexOf('@');intendindex = id.indexOf('.'); String company = id.substring(startindex +1, endindex); ...
String reversal is not a common operation in programming, so many coding languages do not have a built-in function for reversal strings. Reversing a string is one of the most frequently asked questions in a programming technical interview, and it does have a few real-world applications. ...
