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 two, as int
        int varD1 = ____;
        
        // varD2 is varC divided by two, as double
        ____;   
        
        System.out.println("int varD1: " + varD1);
        System.out.println("double varD2: " + varD2);
