String in Java String class overrides equals method and provides a content equality, which is based on characters, case and order. So if you want to compare two String object, to check whether they are same or not, always useequals()method instead of equality operator. Like in earlier examp...
Sometimes, an interviewer might request that you don’t use any other class to check for a palindrome. In that case, you can compare characters in the string from both ends to find out if it’s a palindrome. For example: privatestaticbooleanisPalindromeString(Stringstr){if(str==null)return...

Alternatively, we can utilize Java Streams to achieve the same result with a more concise and functional approach. With Streams, we can easily group and count the occurrences of characters in the string. Here’s how we can implement it using Java Streams: @Test public void givenString_whenUsi...
This post will discuss how to convert a string to a list of characters in Java. 1. Naive solution A naive solution is to create a new list and add elements to it using a for-each loop, as shown below: 1 2 3 4 5 6 7 8
