BooleanOperatorsTest

1. What is the knowledge point of the test? Where is the official document to the knowledge point?
   • Official Document: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html
   • Reading and answering the expected output of the code without running.
   • Performing the logical Boolean operators and bitwise.
2. Why the test failed at first?
   • The expected values are null or incorrect
3. Why you corrected the test that way?
   • I initialized the expected Boolean result.
4. Do you have further questions on this knowledge point?
   • None

CharTypeTest

1. What is the knowledge point of the test? Where is the official document to the knowledge point?
   • Official Document: https://docs.oracle.com/javase/tutorial/java/data/characters.html
   • Learning escape sequence
   • Escaped characters
2. Why the test failed at first?
   • The initialize values are whitespaces
3. Why you corrected the test that way?
   • I initialized the variables to the expected escape character
4. Do you have further questions on this knowledge point?
   • None

FloatingTypeTest

1. What is the knowledge point of the test? Where is the official document to the knowledge point?
   • Official Document: https://docs.oracle.com/javase/8/docs/api/java/lang/Math.html
   • Learning data type conversion
   • Rounding off numbers
   • Check if numbers are real numbers or not
2. Why the test failed at first?
   • The initialized variables are having the MAX Integer value
   • No throw exception overflow and underflow values
3. Why you corrected the test that way?
   • I used short for narrowing casting.
   • Math.Round() for rounding off
   • Math.addExact() for ArithmethicException
   • Throw exception error for non-real numbers.
4. Do you have further questions on this knowledge point?
   • None

IntegerTypeTest

1. What is the knowledge point of the test? Where is the official document to the knowledge point?
   • Official Document: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html, https://docs.oracle.com/javase/8/docs/api/java/lang/Integer.html
   • Learning Primitive data types.
   • Maximum and Minimum values for each data types
2. Why the test failed at first?
   • The expected values are incorrect
3. Why you corrected the test that way?
   • I initialized the expected values to Max and Min value for each data type.
   • addExact method for overflowing and underflowing values.
   • Throw NotImplementedException
4. Do you have further questions on this knowledge point?
   • None
