Difference between == and .equals() in Java:
== is used to compare the memory addresses of objects, while .equals() compares the contents of objects.
Example:
String str1 = new String("Hello");
String str2 = new String("Hello");
System.out.println(str1 == str2); // false (different memory addresses)
System.out.println(str1.equals(str2)); // true (same content)
Input an email from the user. You have to create a username from the email by deleting the part that comes after ‘@’. Display that username to the user.
Example :
email = “mejona@gmail.com” ; username = “mejona”
email = “helloWorld123@gmail.com”; username = “helloWorld123”
Take an array of Strings input from the user & find the cumulative (combined) length of all those strings.
Write a function that takes in age as input and returns if that person is eligible to vote or not. A person of age > 18 is eligible to vote.
