public class Turn{public static void main(String[] args){// Different initial values will be used for testingint x = 1; int y = 1;
// Turn the arrow by 90 degrees
System.out.print("x:", y + 90);System.out.println(x);System.out.print("y: ", x - 1 );System.out.println(y);
// Turn the arrow again
System.out.print("x:", y - 1);System.out.println(x);System.out.print("y: ",x + 90);System.out.println(y);}}
Follow these steps:
Open the Java file Errors.java.
Attempt to compile the program. You'll notice the compilation will fail due
to some errors. Fix all the compilation errors and compile the program
again. Every time you fix an error, add a comment to the line you fixed and
indicate which of the three types of errors it was.
Now run the program. Once again, you'll encounter some errors (this time,
runtime errors). Fix these errors and run the program once again to see if
it works.
Now run the program and notice the output. You'll notice that there are
some logical errors in the code. Fix these errors and run the program once
again to see if it now correctly displays what it should.
public class Errors{public static void main (String[] args){System.out.println("Welcome to my first program!\n")String ageStr = "24 years";int age = Integer.parseInt(ageStr);System.out.println("I'm " + age + " years old.");int three = "3";int answerYears = age + three;System.out.println("Total number of years: " + answerYears);int answerMonths = answerYears * 12; System.out.println("In 3 years and 6 months, I'll be " + answerMonths + " months old");//Once you've corrected all the errors, the answer should be 330.}}
