We will discuss String Replace and String Split in Java with some examples. String replace is the process by which we replace parts of a string with another string. Some Java methods directly accept character sequences, while some others accept a regular expression (regex). We will discuss some of these approaces using examples. String split is the process by which a string is split around a delimiter.
