Recursion in java

public class MyClass {
public static void main(String[] args) {
    System.out.println(fact(5));
   
}   

public static long fact(long n){
    if(n <= 1){
        return 1;
    }
    else{
        return n*fact(n-1);
    }
}

}

Output:
120

concat Method of String

public class MyClass {
public static void main(String[] args) {
    String str1 = "harry";
    String str2 = "jerry";
    System.out.println(str1.concat(str2));
}   
}
 Output:
harryjerry

indexOf Method of String

public class MyClass {public static void main(String[] args) {
    String str = "harryjerryharryjerryharry";
    System.out.println(str.indexOf('e'));
}   
}

Output:
6


The method str.indexOf('e') will return the index of letter e of first occurrence in the string


Another example:
public class MyClass {
public static void main(String[] args) {
    String str = "harryjerryharryjerryharry";
    System.out.println(str.indexOf("yj"));
}  
}
Output:
4

            }
        }
    }
}


Output:
tom starts with to
tomato starts with to

Esoteric programming language

An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the language being adopted for mainstream programming, although some esoteric features such as visuospatial syntax have inspired practical applications in the arts. Such languages are often popular among hackers and hobbyists. This use of esoteric is meant to distinguish these languages from more popular programming languages.
Usability is rarely a high priority for such languages; often quite the opposite. The usual aim is to remove or replace conventional language features while still maintaining a language that is Turing-complete, or even one for which the computational class is unknown.
