while (boolean-expression) {

Answer 1

A “boolean-expression” is an expression that returns a boolean value (true or false). The term “nested-statements” refers to the statement(s) inside the while-loop.

For instance:

int x = 10;
while (x > 0) { // x > 0 is an expression with a boolean result
   System.out.println(x); // nested statement 1
   x--;                   // nested statement 2
}

(This will print 10, 9 .. 1 to the console).
