Answer 1

Question 4

1. 4 + 2 = 42
2. Runtime error because this is not a comaptible format for "printf" function.
3. runtime error because %d is missing in the statement and thus there is no variable to assign a value 350 to.
4. The given statement is correct and hence True.
5. false
6. 4+2 = 4+2

Q5. int[] evenNumbers = {2,4,6,8,"Ten"} is NOT VALID in Java as we declared an array of integer data type (namely evenNumbers) but assigning a string "Ten" in it is invalid.
