I have a 1D array of numbers and need help splitting them into groups using a jagged array so that I can perform a series of computations. e.g.
int array []={1 2 3 4 5 6 7 8 9 10} I want to segregate and allocate the first four to one array, the next three to another, and the final three to a third. In my code, I was expecting to obtain something like this.
int [][] x = new int [3][]; x[0] = new int [4]; x[0] = {1 2 3 4}; x[1] = new int [3]; x[1] = {5 6 7}; x[2] = new int [3]; x[2] = {8 9 10}; Is there any method to create this jagged array using a flexible for loop and divide it into M groups or N groups of N values each just like an example given here that I didn’t understand? I attempted to retrieve those numbers using substring(), but I’m not sure how. I attempted to get those numbers using substring(), but I’m not sure how to proceed or if I’m doing it correctly.
for( int i=0; i<x.length; i++) { x [i]= array.substring (0,3); x [i]=array.substring (4,6); x [i]=array.substring(7,9); } I’m new to programming, but this code is plainly incorrect; could you kindly assist me? Thank you very much.
