System.out.println(“Enter any number to check whether the number is EVEN or ODD ?”);
int n = sc.nextInt();
if(n%2==0)
{
System.out.println(“You entered an Even number : “+n);
}
else
{

String example in java:-
package SeleniumLearn.Com;
public class StringExample {
public static void main(String[] args) {
// Create Strings
String k1=”Java and Selenium on seleniumlearn.com “;
String k2= new String (“I Love Selenium and Java”);
char arr[] = {‘w’,’w’,’w’,’.’,’s’,’e’,’l’,’e’,’n’,’i’,’u’,’m’,’l’,’e’,’a’,’r’,’n’,’.’,’c’,’o’,’m’};
String k3=new String(arr);
// Display all the 3 Strings
System.out.println(k1);
System.out.println(k2);
System.out.println(k3);
// Find length of k1 string
System.out.println(“Length of k1=”+k1.length());
// Adding two k1+k2 strings
System.out.println(“k1 and k2 added=”+k1.concat(k2));
//Concatenate k1 string with k3
System.out.println(k1+”Visit–> “+k3);
// Test if string k2 start with I
boolean b=k2.startsWith(“I”);
if(b) System.out.println(“k2 string starts with \’I\'”);
else System.out.println(“k2 string does not start with \’I\'”);
//Extract substring from k2, starting from 8th char to 23rd char
String p =k2.substring(7,24);
//Extract substring from k3, starting from 3rd char to 12th char
String q =k3.substring(3,12);
System.out.println(p+q);
//convert k3 into upper case to lower case and upper case to lower case.
System.out.println(“Lower case = “+k3.toLowerCase());
System.out.println(“Upper case = “+k3.toUpperCase());
// Check if k1 string equal to k2 string
if (k1==k2)
System.out.println(“k1 & k2 strings are same”);
else System.out.println(“k1 & k2 strings are NOT same”);
// Check given number even or odd
String original = “moc.nraelmuineles.www”;
System.out.println(“Original String : ” + original);
original = new StringBuffer(original).reverse().toString();
System.out.println(“Reversed String : ” + original);
}
}
O/P:-
