![]() In other words, the newly created string object is a copy of the argument string.ġ2. String(String value): It initializes a newly created string object with the same sequence of characters as the argument string. String(int codePoints, int offset, int count): This constructor allocates a new string object that contains characters from a subarray of the Unicode code point array argument.ġ1. String(char value, int offset, int count): This form of constructor allocates a new String that contains characters from a subarray of the character array argument.ġ0. ![]() String(char value): This form of constructor allocates a new String so that it represents the sequence of characters currently contained in the character array argument.ĩ. String(byte bytes, String charsetName): It creates a new string object by decoding the specified array of bytes using the specified charset.Ĩ. String(byte bytes, int offset, int length, String charsetName): This constructor constructs a new string object by decoding the specified subarray of bytes using the specified charset.ħ. String(byte bytes, int offset, int length, Charset charset): This form of constructor creates a new string object by decoding the specified subarray of bytes using the specified charset.Ħ. String(byte bytes, int offset, int length): This form of constructor creates a new string object by decoding the specified subarray of bytes using the platform’s default charset.ĥ. String(byte bytes, Charset charset): It creates a new string object by decoding the specified array of bytes using the specified charset.Ĥ. String(byte bytes): This constructor constructs a new string object by decoding (or converting) the specified array of bytes using the platform’s default charset.ģ. String(): This constructor creates an empty String.Ģ. String class provides several constructors in java but for the purpose of exam, we only need to be aware of the following constructors.ġ. String in Java is final class, which means it cannot be extended. This class also implements three interfaces, such as CharSequence, Comparable, and Serializable. So, in addition to the functionality provided by String class, string can also use all the functionality provided by the Object class and can override them. Implements Serializable, Comparable, CharSequence The general syntax to declare a string class in java is as follows: public final class String ![]() When we create a string directly in double quote without using constructor, that string is stored in a special area of heap space known as “string constant pool”. In Java world, String instances/objects are usually just called “strings”.Īs we recall, all strings are stored in heap space when we create string using constructors defined in the class. That is, it is used to store multiple characters.įor example, strings such as “12346” and “hello world” are really instances of this class. ![]() String class in Java is used to represent character strings. This string class helps to manage text strings effortlessly in the java program. To support character strings, Java programming language provides a string class. In an application or a program, it is common to work with the sequence of text character (e.g., for user interactions or data processing). ![]()
