what do you mean by statically-typed programming language?

Answer 1

It means the data type is known at the time the variable is declared so the compiler can verify that only the correct usage is performed and it can not be changed during the execution of the program. Most languages require the type to be hard coded such as:

int number = 5;

Some can tell 5 is of type int so don't require the type, but in all cases you can never turn around and assign an array to the variable.
