Java Java Basics Getting Started with Java Strings and Variables

I am using eclipse as it is used in my institution and we dont use %s or something for string instead we use the variabl

What is the difference in using a %s for printing a string? we use the variable name instead like : String name ="abcd" System.out.print("My name is " + name);

You're quite right.

Java gives you different way to combine variable and String together, what you're doing here is called string concatenation, you're concatenating String and variable together using the + sign; another way is called String interpolation, you're inserting variable into a String using the %s formatter.

They both get the job done equally well, usually which one to use is just a matter of style, though I wanna say that if you're inserting lots of variables into a string, using String Interpolation probably makes it a bit easier to figure out how the output String gonna be by looking at the code.
