Note: the index starts from ‘0’ which refer to the first character of String. If the endIndex is not passed, the substring begins with the character at the specified index and extends to the end of the string. The substring begins with the character at the startIndex and extends to the character at index endIndex - 1. The substring begins with a character at the specified index ‘beginIndex’ to the end of the string. The substring () method returns a substring from the given string. This method has two variants and it returns a new string that is a substring of this string.
Here, the string is “Edureka” but when you break it down into blocks, it’s composed of substrings which finally compute the string. This is a clear example of a substring in Java. It takes two arguments the start index, which specifies the index where the. substring() method is an overloaded method. To create a substring in Java, you must use the getSubString() method. The Java substring () method returns a new string that is a substring of this string. In other words, substring is a subset of another string.
Substring in Java: What is a substring in Java?Ī part of a stringis called a S ubstring. substring(int beginIndex, int endIndex).These are the topics that I’ll be covering in this article: So, I’ll explain how Substring in Java works. In Java, objects of a String are immutable which means that a constant cannot be changed once created. Finding the substring of a string is a very common question asked in the Java interviews. Strings are basically defined as an array of characters.
