Question

Check the Vehicle!

Assume that vehicles are going through a two-way traffic intersection. There are three types of vehicles: car, motor bikes and trucks. Generate a series of 10 random integers, between 1 and 3, inclusive. The numbers represent the type of vehicle as stated below:

Number Vehicle Category
1 Car
2 Motor bikes
3 Trucks

Write a program, using a for loop, to count how many vehicles going through the traffic intersection are cars, motor bikes and trucks. Then, the program should print out the numbers for each vehicle category. There is no user input for this program.

Answer 1

java programming

Answer 2

I did this int car;
int motorbikes;
int trucks;
int randNum=0;
randNum=(int)(Math.random() * +1);
for(int a = 1; int a =10; a++)
{
System.out.print(a);
}
if(randNum = 1 && a=10)
System.out.println("Number of Cars ");
else if(randNum = 2 && a=10)
System.out.println("Number of MotorBikes ");
else if(randNum = 3 && a=10)
System.out.println("Number of Trucks ");
}

Answer 14

int cars;
int motorbikes;
Main Class ()
int trucks;
counter=0
randNum=(int)(Math.Random()* 3)+1;
for (int a=0;a<10;a++)
{ if(a=1; a<10)
System.out.println("a"+ car);
}
else if(a = 2; a<9; a++)
{ System.out.println("a" + Motor Bikes);
}

else if (a=3; a<8; a++)

{
System.out.println("a" + Trucks);

}

System.out.println("Number of cars = +cars");
System.out.println("Number of MotorBikes = +motorbikes");
System.out.println("Number of Trucks = +trucks");
