Program rearranged
// QuartsToGallons.java
public class QuartsToGallons
{
public static final int QUARTS_IN_GALLON = 4;
public static void main(String[] args)
{
int quartsNeeded = 18;
// finding required quarts
System.out.println("A job that needs " + quartsNeeded + " quarts requires " + (quartsNeeded / QUARTS_IN_GALLON) + "gallons plus " + (quartsNeeded % QUARTS_IN_GALLON) + "quarts");
}
}
Answer:
The output of the program is
A job that needs 18 quarts requires 4 gallons plus 2 quarts
Step-by-step explanation:
From the rearranged program above
At line 3, a global variable named QUARTS_IN_GALLON is declared
The Variable is declared as an integer
And the Variable is initialised to 4
At line 5, a local Variable is declared
The Variable is declared as an integer
And the Variable is initialised to 18
At Line 7, some arithmetic operations are done and the result of the Calculation is printed alongside some strings
The first operation is quartsNeeded/QUARTS_IN_GALLON
This is an integer division and the result will be in integer.
So, 18/4 = 4
The second operation is quartsNeeded%QUARTS_IN_GALLON
This means the remainder of the integer division
So 18%4 = 2
Then, the final step is to execute the print operation which outputs the following
A job that needs 18 quarts requires 4 gallons plus 2 quarts
