In java, string is an immutable object which means it is constant and can cannot be changed once it has been created. In this tutorial we will learn about String class and String methods in detail along with many other Java String tutorials. As I stated in the beginning that String is an object in Java.

However we have not created any string object using new keyword above. For example there are 10 string instances that have same value, it means that in memory there is only one object having the value and all the 10 string instances would be pointing to the same object. What if we want to have two different object with the same string? As we saw above that when we tried to assign the same string object to two different literals, compiler only created one object and made both of the literals to point the same object. In this case compiler would create two different object in memory having the same string.

Here are the list of the methods available in the Java String class. These methods are explained in the separate tutorials with the help of examples. It returns the character at the specified index. Compares the string with the specified string and returns true if both matches else false. It works same as equals method but it doesn’t consider the case while comparing strings. It does a case insensitive comparison.

This method compares the two strings based on the Unicode value of each character in the strings. It tests whether the string is having specified prefix, if yes then it returns true else false. Checks whether the string ends with the specified suffix. It returns the hash code of the string. Returns the index of first occurrence of the specified character ch in the string. It returns the last occurrence of the character ch in the string.

This method returns the index of first occurrence of specified substring str. Returns the index of last occurrence of string str. It returns the substring of the string. The substring starts with the character at the specified index. It checks whether the string contains the specified sequence of char values. If yes then it returns true else false.

Converts the string to upper case string using the rules defined by specified locale. This method searches the specified string in the memory pool and if it is found then it returns the reference of it, else it allocates the memory space to the specified string and assign the reference to it. This method returns true if the given string has 0 length. If the length of the specified Java String is non-zero then it returns false.
