simulate: input: null output: boolean tells you if the distance in the hopdistance reaches the goal in the needed amount of moves runSimulate: input: null output: percent of simulates that finish the goal.

A1: JVM is the Java Virtual Machine. To compile the c ode, a compiler is used. It turns your code into "machine language," and then the JVM reads the class file and turns it into binary, so that your computer can run your code. D3: This will print out 10lb because the first two are integers. The second one will print $46 because the first character is a string. If you wanted to do $10, add parentheses around the 4 and 6.
