In this post, we will see java program to find allsubstringsof a String. For example: If input is “abb” then output should be “a”, “b”,”b”, “ab”, “bb”, “abb” We will use String class’s subString method to find all subString ...
program creates references to objects that are not needed anymore, it will not be freed. In a way, we can still call this memory leak. Memory leaks in Java can happen in various ways, but the most common reason is everlasting object references, because the garbage collector can’t remove ...
