Definition:
Concatenation is the process of combining any and all of data types (strings, integers, doubles or floats, chars, a even a boolean).
Syntax:
Here is some examples of how concatenation works and when to use it:
String firstName = "John";
String lastName = "Smith";
String fullName = firstName + " " + lastName;
String gender = "Male";
int age = 25;
int phoneNumber = 1234567890;
int SSN = 101010101;
Boolean isMarried = true;
System.out.println("Full Name is: " + fullName );
System.out.println("Age is: " + age + " years old" );
System.out.println("Gender is: " + gender );
System.out.println("Is married?: " + isMarried );
System.out.println("Phone number: " + phoneNumber );
System.out.println("SSN: " + SSN);
// output:
/*
Full Name is: John Smith
Age is: 25 years old
Gender is: Male
Is married?: True
Phone number is: 1234567890
SSN: 101010101
