When assigning a new array to a declared variable, new must be used. Even if you correct the syntax, accessing ...
Whenever we write int[] array = new int[10], this simply initializes an array of size 10 having all elements set to 0, but I just want to initialize all elements to something other than 0 (say, -1). Otherwise I have to put a for loop just after the initialization, which ranges from index 0 to index size − 1 , and inside that loop assign each element to the desired value, like this:
Dec 4, 2013 · String[][] myStringArray = new String [x][y]; is the correct way to initialise a rectangular multidimensional array. If you want it to be jagged (each sub-array potentially has a different length) then you can use code similar to this answer.
