1. [5pts] In the following main method:
public static void main(String[] args)
{
//Input any 3 integers
Scanner input = new Scanner (System.in);
System.out.print("Enter an integer -> ");
int a = input.nextInt();
System.out.print("Enter an integer -> ");
int b = input.nextInt();
System.out.print("Enter an integer -> ");
int c = input.nextInt();
int max;
if (a > b && a > c)
max = a;
else if (b > a && b > c)
max = b;
else
max =c;
System.out.println("Maximum of the input values is: "+
max);
}
Suppose inputs are 20, 30 and 10. Output: ___30___
Suppose inputs are 20, 20 and 5. Output: ____5___
Is the logic correct? If not, please rewrite the conditional statement.
No.
change “>” to “>=” in the if else statements
2. [5pts] In the following main method:
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);
System.out.print("Enter the Tire Pressure (0..75 psi)
-> ");
int pressure = input.nextInt();
System.out.print("Pressure: " + pressure + " psi : ");
String state = "Pressure OK";
//30..35:OK
//under 30 : UNDERinflated
//over 35 : //OVERinflated
if(state < 30)
state = “UNDERinflated”;
else if(state > 35)
state = “OVERinflated”;
}
The above main method is designed to illustrate testing “boundary conditions”.
The program allows the user to enter a tire pressure in psi (pounds per square
inch) and prints “Pressure OK” if the pressure is in the range 30..35, inclusive.
Otherwise, the program should print one of the messages “UNDERinflated” or
“OVERinflated”, whichever is appropriate. Complete the program using
appropriate logic.
