JAVA String Operators

In Java, there aren’t specific “string operators” like you might find in languages like JavaScript or Python. Instead,
Java primarily relies on methods and concatenation to perform operations on strings. Here are some common
string operations and techniques in Java:
For Example:-
1 Concatenation Operator +:

• You can use the + operator to concatenate (join) strings together.
String firstName = “John”;
String lastName = “Doe”;
String fullName = firstName + “ “ + lastName;

Example
class Concat_Operator {

public static void main( String args[] ) {
String first = “Hello”;
String second = “World”;

String third = first + second;
System.out.println(third);

// yet another way to concatenate strings
first += second;
System.out.println(first);

}
}

Output

2 Concatenation with Other Data Types
• You can also use the + operator to concatenate strings with other data types, which automatically converts the
non-string operands to strings.

int age = 30;
String message = “My age is “ + ag

Example
public class Demo {
public static void main(String args[]){
String st1 = “Hello”;

int age = 500;
