This method replaces the first substring of this string that matches the given regular expression with the given replacement. In this page, we will learn about Java exceptions, its type and the difference between checked and unchecked exceptions. readLine(): Reads the next line of text from this file. a) 35721 b) 354721 c) 3521 d) 35 Ans. The Exception Handling in Java is one of the powerful mechanism to handle the runtime errors so that normal flow of the application can be maintained. This allocates a new String that contains characters from a subarray of the character array argument. We can perform many operations on strings such as concatenation, comparision, getting substring, search, trim, replacement etc. This method tests if the substring of this string beginning at the specified index starts with the specified prefix. Creating a String. The string is a sequence of characters. File(URI uri) : Creates a new File instance by converting the given file: URI into an abstract pathname. This method compares this String to another String, ignoring case considerations. This constructs a new String by decoding the specified array of bytes using the platform's default charset. This method returns the index within this string of the last occurrence of the specified character. This method returns the index within this string of the first occurrence of the specified character. This method concatenates the specified string to the end of this string. This method converts all of the characters in this String to lower case using the rules of the default locale. This method compares two strings lexicographically, ignoring case differences. What is Exception in Java. You can perform operations over it without storing those values. Live Demo All objects thrown by components of the standard library are derived from this class. In java, objects of String are immutable which means a constant and cannot be changed once created. This method returns a canonical representation for the string object. The most direct way to create a string is to write −. A string in Java is immutable, i.e., once created, their values cannot be changed. This allocates a new String that contains characters from a subarray of the Unicode code point array argument. The basic aim of String Handling concept is storing the string data in the main memory (RAM), manipulating the data of the String, retrieving the part of the String etc. This method tests if this string starts with the specified prefix.
