I am completely new to coding and have no clear idea what I am doing. I have a code for my Finch robot that simply makes it move left and right, but how do I make this simple process loop for three times? Additionally, can a code be implemented to ask the user how many times do they want the product to loop?
Sorry if this seems like a stupid question. I've looked everywhere and don't quite understand how to loop a code properly. The code that I want to loop is posted below.
public static void main(final String[] args)
{
Finch myFinch = new Finch();
myFinch.setLED(Color.green);
myFinch.setWheelVelocities(180, 0, 750);
myFinch.setWheelVelocities(100, 100, 1500);
myFinch.setLED(Color.red);
myFinch.setWheelVelocities(0, 180, 850);
myFinch.setWheelVelocities(180, 180, 1500);
myFinch.quit();
System.exit(0);
}
First Approach: Using for loop
public static void main(final String[] args)
{
Finch myFinch = new Finch();
Scanner sc = new Scanner(System.in);
System.out.println("How many times?");
int noOfTimes = sc.nextInt();
for(int movement=0; movement < noOfTimes; movement++){
myFinch.setLED(Color.green);
myFinch.setWheelVelocities(180, 0, 750);
myFinch.setWheelVelocities(100, 100, 1500);
myFinch.setLED(Color.red);
myFinch.setWheelVelocities(0, 180, 850);
myFinch.setWheelVelocities(180, 180, 1500);
}
myFinch.quit();
System.exit(0);
}
Second Approach: Using while loop
Scanner sc = new Scanner(System.in);
System.out.println("How many times?");
int noOfTimes = sc.nextInt();
while(noOfTimes > 0){
myFinch.setLED(Color.green);
myFinch.setWheelVelocities(180, 0, 750);
myFinch.setWheelVelocities(100, 100, 1500);
myFinch.setLED(Color.red);
myFinch.setWheelVelocities(0, 180, 850);
myFinch.setWheelVelocities(180, 180, 1500);
noOfTimes--;
}
Third Approach: Using do-while loop
Scanner sc = new Scanner(System.in);
System.out.println("How many times?");
int noOfTimes = sc.nextInt();
do{
myFinch.setLED(Color.green);
myFinch.setWheelVelocities(180, 0, 750);
myFinch.setWheelVelocities(100, 100, 1500);
myFinch.setLED(Color.red);
myFinch.setWheelVelocities(0, 180, 850);
myFinch.setWheelVelocities(180, 180, 1500);
noOfTimes--;
}while(noOfTimes > 0);
