String subStr = strEx.substring(int startIndex, int endIndex) The second way returns a substring as a new String object formed by chars from the start index, up to but not including the end index, in the original string. String subStr = strEx.substring(int startIndex) The first approach returns a substring as a new String object formed by chars between the start index value (inclusive) and the end of the original string. Due to the string data type’s immutability property, we will have to store any substring in Java that we extract from an existing String object in a new String variable. Substrings represent an ordered sequence of characters that we can extract from a Java String object. Note: The methods we cover in this article were coded with Java 11. This tutorial provides various code examples and walkthroughs for the built-in Java substring method. When it comes to Java, we have access to a range of string methods that are part of the String class. As one of the most widely used data types, strings are often the focus of Java coding interview questions via string manipulation problems, whether that be string reversal, conversion, string splitting, or extracting substrings. The Java String data type uses a sequence of characters (char data types) to store all sorts of text-like data.
