The String class has a set of built-in methods that you can use on strings.

January 31, 2024 - In the above example, we have created 3 strings named first, second, and third. Here, we are using the equal() method to check if one string is equal to another. The equals() method checks the content of strings while comparing them. To learn more, visit Java String equals().

August 9, 2026 - The intern() method is one of the built-in Java string functions that returns the canonical representation of a given string. It is helpful in the string pool. The intern () method looks inside the string pool for the value, if it exists, references that subject; otherwise, it creates a new string with this text inside a string pool. public class example { public static void main(String[] args) { String s1 = "USA"; String s2 = new String("USA"); System.out.println(s1 == s2); System.out.println(s1 == s2.intern()); } }

public boolean isEmpty(): 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.

Java string class methods are used to perform operations on string variables or string literals like compare two strings, find or replace a character/word in a string, add two strings etc.

July 18, 2026 - Literals and the pool: When the class loads, the JVM sees the literal "Java" and either adds it to the string pool or reuses an existing entry. Any other occurrence of the identical literal in your compiled code reuses that same reference. Calling a transforming method: A call like trimmed.substring(7) does not touch trimmed's backing array.

April 1, 2025 - In this example, we have taken an input String as “StringJavaAndJavaStringMethodsJava”. Then we have initialized a subString as “Java” with a counter variable and the index as 0. Then we have used the indexOf() method with the help of a while loop to check each index and incrementing it after every iteration.

January 19, 2022 - 5 - replace() Used for replacing characters and substrings in a string syntax - public String replace​(char oldChar, char newChar) ▶️ Example : remove all white spaces from the string

June 15, 2022 - The string is an immutable class. This is the most important definition to remember. Immutable means that once created with some value we cannot change it. Just to be clear we can reassign the value of reference(as shown in the above example with str) but the original object that was created in the beginning will never get changed.

October 24, 2024 - In Java Programming, strings are widely used and treated as objects, and string in Java can not be changed once it has been created. There are several methods in Java that assist in performing operations in a string called String functions. In this article, we will explore various string methods along with detailed examples.

Java has a lot of String methods that allow us to work with strings. In this reference page, you will find all the string methods available in Java. For example, if you need to find the length of a string, use the length() method.

May 24, 2024 - Java provides the StringBuilder and StringBuffer classes for mutable strings. The length() method returns the length of the string.

August 11, 2026 - String class in Java already have a toString method and it returns the String representation of the given object. You can also use the toString method to convert a variable into a string.

August 12, 2026 - Learn Java String Methods with examples. Explore the list of String functions, syntax, common operations & practical programs to master String methods in Java.

August 23, 2025 - The string has a similar class method named format (). It yields a String object. In contrast to the one-time print command, the static format () method accessible in the String object permits the construction of a formatted string that may be reused. ... In this section, we have discussed some examples of string functions in Java.

October 20, 2022 - For example, to find out the number of characters contained in the string object, length() method can be used instead of iterating over all characters and increasing the count one at a time. Let’s dive deep into the most commonly used Java string methods and understand their working. Used to find characters and substrings in a string. It returns the index of the first occurrence from the left of the passed string within this string; moreover, if we provide the fromIndex, it starts searching from that index.

May 18, 2026 - Confusing equals() with ==: The equals() method compares the content or value of two strings, while the == operator compares object references in memory. Use equals() to check for string equality. Java Strings are extremely common as data entries in applications, and managing them is an important task.

June 15, 2024 - In this example, a for loop iterates over each character in the string, and the charAt method is used to extract and print each character. Comparing strings is another fundamental operation in Java.
