The substring() method in Java does not create memory leaks by itself. However, if the original String object is modified after a substring is created from it, then both the original and the substring will reference the same underlying character array. When one of them goes out of scope (due to garbage collection), the other might still hold a reference to it, causing a memory leak. To avoid this issue, create new String objects for each substring.
