JAVA Program to check whether a given string is palindrome or not without taking the concept of reverse

.import java.util.*;
class StringPalindrome {

public static void main(String[] args)
{
String str;
int l,c=0;
Scanner s= new Scanner(System.in);
System.out.println("enter a string");
str= s.nextLine();
l=str.length();
for(int i=0;i<(l-1)/2; i++)
{
if(str.charAt(i)==str.charAt(l-1-i))
{
continue;
}
else
{
c++;
}
}
if(c==0)
System.out.println("the given string is a pallindrome");
else
System.out.println("the given string is a not pallindrome");

}

}

Output
enter a string
katak
the given string is pallindrome

Interface in JAVA 8(JDK 1.8 version)

It is possible to define method inside the interface by implementing default method or static method in JAVA 8.

Example1: using default method:

package test;

interface A{

default void show()

{

     System.out.println("java");

}

}

class B implements A

{

    

}

class InterfaceExample1

{

     public static void main(String[] args)

     {

          B obj=new B();

          obj.show();

     }

}

Output

java

Example2: Using static method:

package test;

interface A{

static void show()

{

    System.out.println("java");

}

}

class InterfaceExample2

{

    public static void main(String[] args)

    {

        A.show();

    }

}

Output

java
