To answer your question “How to return the matrix”: you are already doing it the right way. As you can see from the comments so far, the problem lies in the declaration of A<\/code>.<\/p>\n

A<\/code> is declared and initialized inside the for<\/code>-loop:<\/p>\n

int [][]A = new int [size_num][size_num];\n<\/code><\/pre>\n
Hence its visibility is limited to the for<\/code>-loop. To make A<\/code> visible to the already existing return<\/code> statement you have to move its declaration:<\/p>\n
int size_num = Integer.parseInt(size);\nint[][]  A = new int[size_num][size_num];\nif (size_num > 1 && size_num < 4) {\n  BufferedReader br = new BufferedReader(new InputStreamReader(System.in));\n  for(int row = 0; row < size_num ; row++)\n    for(int col = 0 ; col < size_num ; col++){\n        String ipS = br.readLine();\n        int input_value = Integer.parseInt(ipS);\n        A[row][col] = input_value;\n  }\n} else {\n  System.out.println(\"invalid matrix size!\");\n}\nreturn A; \n<\/code><\/pre>\n<\/p><\/div>\n
