Creating a JAVA program which should implement a method that verifies whether a given 4 x 4 square (containing 16 values) is a Magic Square with a given magicValue.

The code here is good to solve for verifying if it is a magic square but not n generating a new Magic Square, it is not as in the picture. The sum in row and columns are not equal.
