Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
class BasicMaths {
public static void main(String[] args) {
// Save the result of 5 plus 6 to varA
int varA = ____ ____ ____;
// varB is varA minus 3.5
double varB = ____;
// varC is 3 times 3
____;
// varD1 is varC divided by three, as int
int varD1 = ____;
// varD2 is varC divided by three, as double
____;
System.out.println("int varD1: " + varD1);
System.out.println("double varD2: " + varD2);
