It is something that holds a value.
ex:
string holds text.
char holds one character.
integer holds numbers.

They can be declared by...
string myWords = "Hello, World!";
System.out.println(myWords);
This code will make a console say whatever is inside of that variable, which happens to be: "Hello, World!".
