When utilizing the substring() method in Java, it becomes possible to extract a specific subset of characters from a given string. Return checkPal(pStr.substring(1, pStr.length() - 1)) If (!pStr.substring(0, 1).equals(pStr.substring(pStr.length() - 1))) Public static boolean checkPal(String pStr) By leveraging the substring() method with a single parameter, developers can effortlessly obtain a new String object representing the desired substring. This functionality proves useful when there is a need to isolate a portion of a String, beginning from a specific position and extending to the end. The last character of the original String is also included in the extracted substring. When using this form of the substring() method, a new String object is created, containing the characters starting from the specified startIndex and continuing until the end of the original String. The substring() method in Java, when invoked with a single parameter, allows for the extraction of a new String object starting from the specified startIndex (inclusive) and extending to the end of the original String, encompassing the last character of the String. This variant extracts the characters between the starting and ending indices from the original String. This variant extracts the portion of the String starting from the specified index to the end of the String.Īnother version of the substring() method takes two parameters, denoting the starting index and the ending index (exclusive) of the desired substring. One version takes a single parameter, representing the starting index of the substring. The substring() method in Java offers flexibility by accepting different variations of parameters. There are two ways you can use the Java substring() method This new String object is created based on the original String and contains the characters specified by the substring parameters. When the substring() method is invoked, it returns a brand new String object that represents the extracted substring. In Java, the String class provides a substring() method that facilitates the extraction of a specific substring from a given String. The substring refers to a portion or fragment extracted from a larger String. The concept of substrings holds significance when dealing with Strings.
