Strings are nothing but the sequence of characters that are widely used in the programs. A string is one of the default class in Java which had the capability of binding the characters to form a word. When JVM finds String name in the program it will create an object for the String class.
There is no need for a developer to create an object for the String class.
Variable with type String
class Display { public static void main(String[] args) { String b = "This is a variable of type string" System.out.println(b) } }
Method with String type
public class DisplayCheck { static String check = "String check"; String display(String s) { return s; } public static void main(String[] args) { DisplayCheck d = new DisplayCheck(); System.out.println(d.display(check)); } }Below is some of the list of methods that can be used to do various actions on the String
- .length() - This is used to find the length of the string
- .concat() - Using this method it will be easy to join 2 string values
- .equals() - Used to check 2 strings are equal or not
public class DisplayCheck { static String check = "String check "; static String con = "Combine this to checked"; String display(String s) { return s; } public static void main(String[] args) { DisplayCheck d = new DisplayCheck(); System.out.println("Lenght of the string is " +d.display(check).length()); System.out.println(d.display(check).concat(con)); } }
In the later part of the article, we will see advanced methods
