Question

This is a praxctice assignment I have to do in Scratch but I don't know where to start.

Timer 1. Create a variable called timer. 2. When the green flag is clicked, initialize the timer to 10. 3. Continually, wait 1 second and check if the timer=0 a. Output the current time b. If the timer=0 make either the background or a huge sprite say “time’s up!” 4. When the flag is clicked, everything should start over. 5. Be as creative as you would like with how your program looks. 6. Make sure your timer stops at 0 and does not continue into the negative numbers.

Answer 1

I AM DOING IT IN JAVA IT IS VERY SIMILAR TO SCRATCH :-(WITH LINE BY LINE EXPLANATION)

void timers( String flag) #this is the function

{

int timer; #this is the timer variable

timer=Integer.parseInt(in.nextLine()); #taking the input from the user

if(flag=="green") #if flag is green we go to the loop

{

for(int time=10;time>0;time--); #here the time is intiliazed to 10 and it is gradually decresing. time will always     n# it will always be more than zero

}

if(time==0)

{

System.out.println("Timesup!"); #if the time is zero we will print timesup!

}

}

static void main() #this is the driver function

{

String flag;

for(int i=0;i<5;i++) #we ask the user to enter the value in flag

{

Scanner in=new Scanner(System.in);

flag=in.nextLine();

if(flag=="green") # if flag is clicked we again call the timer function

timer(flag);

}

}
