A char is a numeric primitive - its a 16 bit number that's used to hold a Unicode value representing an individual character in some chosen characterset. Primitives like char do not have methods.
A String is an Object that holds some text as a (private) array of chars and has many methods for working with them.
"Parse a String into a char" just doesn't make sense. A String of length n contains n chars.
If you want to get a char from some text input stream or String array you have to ensure that the String is of length 1, then get that one char from the String using its charAt method.
Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...
I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
