Why we are putting + sign in the start of variable and sometimes both ends variable

Why we are putting + sign in the start of variable and sometimes at both ends of the variable?
For example:
System.out.println("Employee id:" +id+ "Name:" +name);
For example:
System.out.println("Employee id:" +id+ "Name:" +name);

+ sign is used to concatenate values of variables with the string e.g. in your if id variable has value 3 then it would be concatenated as "Employee id:3"
