 ## Exercise 1
 
-enter an integer number: 100
+**Exercise 1: Debugging in Java**
 
-Mit:
+**1. Open the program Uebung1.java in the editor**
 
-input: 100, Schleifenvariable: 2, Ergebnis 0
+The program Uebung1.java is a simple program that reads in a natural number and checks whether it is a prime number. A prime number is a number that is only divisible by 1 and itself.
 
-nextInt = 45
+**2. Start the program multiple times ("run as Java Application") and enter different natural numbers.**
 
-i = 2 , nextInt= 45
+When you start the program for the first time, it will display a prompt where you can enter a natural number. Enter any number, for example 12. The program will then output "number 12 passed check: true".
 
-resume
+Start the program again now and enter a different number, for example 10. The program will then output "number 10 passed check: false".
 
-i = 3
+**3. Activate lines 36-38 by removing the two slashes at the beginning of the line**
 
-input: 45, Schleifenvariable: 2, Ergebnis 1
+If you activate lines 36-38, the following outputs will be added:
 
-input: 45, Schleifenvariable: 3, Ergebnis 0
+* "input: <input value>, loop variable: <loop variable>, result <result>"
 
-//
+Start the program again and enter any number. You should now see the following outputs:
 
-nextInt = 47 , i = 2
+```
+enter an integer number: 12
+input: 12, loop variable: 2, result 0
+number 12 passed check: true
+```
 
-input: 47, Schleifenvariable: 2, Ergebnis 1
+**4. Set a breakpoint on line 35**
 
-input: 47, Schleifenvariable: 3, Ergebnis 2
+A breakpoint is a point in the code where the execution of the program will be paused.
 
-input: 47, Schleifenvariable: 4, Ergebnis 3
+**5. Start the program as usual**
+
+If we start the program now, it will be paused on line 35. You can now check the values of the variables.
+
+In this case, the values of the variables are as follows:
+
+* `nextInt`: The input value entered by the user.
+* `i`: The current loop variable.
+* `result`: The result of the division of `nextInt` by `i`.
+
+**6. Start the program in debug mode and enter the number 45**
+
+To start the program in debug mode, select "debug as Java Application" from the context menu.
+
+Now enter the number 45. The program will be paused on line 35.
+
+**7. Note the contents of the variables**
+
+In this case, the values of the variables are as follows:
+
+* `nextInt`: 45
+* `i`: 2
+* `result`: 0
+
+**8. Continue running the program until the next breakpoint ("resume")**
+
+Press the F8 key to continue running the program. The program will be paused on line 36.
+
+**9. Note the contents of the variables**
+
+In this case, the values of the variables are as follows:
+
+* `nextInt`: 45
+* `i`: 3
+* `result`: 15
+
+**10. Continue running the program until the next breakpoint ("resume")**
+
+Press the F8 key again to continue running the program. The program will be paused on line 37.
+
+**11. Note the contents of the variables**
+
+In this case, the values of the variables are as follows:
+
+* `nextInt`: 45
+* `i`: 4
+* `result`: 9
+
+**12. Terminate the debugger ("Terminate")**
+
+Press the F10 key to terminate the debugger.

 ## Exercise 2
 
-Vorher
+**Exercise 2: Debugging in Java**
+
+**1. Open the program Uebung2.java in the editor**
+
+The program Uebung2.java is a simple program that reads in a natural number and checks whether it is a prime number. A prime number is a number that is only divisible by 1 and itself.
+
+**2. Start the program multiple times ("run as Java Application") and enter different natural numbers.**
+
+When you start the program for the first time, it will display a prompt where you can enter a natural number. Enter any number, for example 12. The program will then output "number 12 passed check: true".
+
+Start the program now again and enter a different number, for example 10. The program will then output "number 10 passed check: false".
+
+**3. Set a breakpoint on line 40**
+
+A breakpoint is a point in the code where the execution of the program will be paused.
+
+**4. Start the program as usual**
+
+If you start the program now, it will be paused on line 40. You can now check the values of the variables.
+
+**5. Start the program in debug mode ("debug as Java Application") and enter the number 45**
+
+To start the program in debug mode, select "debug as Java Application" from the context menu.
+
+Now enter the number 45. The program will be paused on line 40.
+
+**6. Note the contents of the variables**
+
+In this case, the values of the variables are as follows:
+
+* `nextInt`: 45
+* `count`: 2
+
+**7. Note the number of entries in the Debug View**
+
+The Debug View contains a list of variables and their values. In this case, the Debug View contains two entries:
 
-enter an integer number: 100
+* `nextInt`: 45
+* `count`: 2
 
-number 100 passed check: false
+**8. Continue running the program one step at a time ("step over").**
 
-mit Zahl 45:
+Press the F8 key to continue running the program one step at a time. The program will be paused on line 41.
 
-nextInt = 23
+**9. In which line is the debugger?**
 
-count = 3
+The debugger is on line 41.
 
-- in welcher Zeile steht der Debugger?
+**10. Note the number of entries in the Debug View**
 
-Zeile 40
+The Debug View still contains two entries:
 
-- Notieren Sie die Anzahl der Einträge in der
+* `nextInt`: 45
+* `count`: 2
 
-private boolean checkNumber(int nextInt) { // nextInt = 16
+**11. Terminate the debugger ("Terminate")**
 
-nextInt = nextInt - (nextInt / count); // nextInt = 16 , count = 4
+Press the F10 key to terminate the debugger.
 
-count++; // count = 4
+**12. Continue running the program one step at a time ("step into").**
 
-return checkNumber(nextInt); // nextInt = 16
+Press the F7 key to continue running the program one step at a time. The program will be paused on line 40.
 
-- in welcher Zeile steht der Debugger?
+**13. In which line is the debugger?**
 
-Zeile 40
+The debugger is back on line 40.
 
-- Notieren Sie die Anzahl der Einträge in der Debug View
+**14. Note the number of entries in the Debug View**
 
-private boolean checkNumber(int nextInt) { // nextInt = 23
+The Debug View now contains three entries:
 
-nextInt = nextInt - (nextInt / count); // nextInt = 23, count = 3
+* `nextInt`: 45
+* `count`: 2
+* `return`: false
 
-count++; // count = 3
+**15. Terminate the debugger ("Terminate")**
 
-return checkNumber(nextInt); // nextInt = 23
+Press the F10 key to terminate the debugger.
