![]() ![]() The above syntax will produce an error known as IndexOutofBoundsException in the following cases:Ī) When endIndex has a smaller value than a startIndex. The startIndex and endIndex, as discussed, are inputs to the function, of which only the startIndex is taken into account, and the endIndex is excluded. The above syntax shows that string represents an object of the class String. String.substring (int startIndex, int endIndex) ![]() The general syntax of calling a substring in Java is given by: For instance, consider a string named “programming language” then, there exist different substrings of this string like ‘program’, ‘ing’, ‘lang’, ‘language’, etc. Therefore, when this startIndex is called and stored in an initialised variable, the output returns a new string, whereas the original string remains unchanged. The startIndex value of a Java substring is considered when the compiler compiles a code, whereas the endIndex is optional and therefore neglected. A built-in method known as substring() is available in the String class of Java that extracts a substring from the given string where the index values are passed as an argument. ![]() Explore this blog on Substring Java meaning, types, methods, uses, working, syntax, examples and much more!Ī) public string.substring (int startIndex)ī) public string.substring (int startIndex, int endIndex)Ĥ) Conclusion Substring Definition in JavaĪ string extracted from a larger string is known as a Substring. A Substring in Java is a subset of another string. According to the TIOBE Index for the programming community, Java stands as 3rd most used programming language. Strings are represented as objects in Java, and Java can use a String class for creating, editing and manipulating an input string. In Java, a string is defined as something that stores a sequence of characters that are enclosed in double-quotes. ![]()
