GTU OOP Programs - 11
11). Write a program that generate 6*6 two-dimensional matrix, filled with 0’s and 1’s , display the matrix, check every raw and column have an odd number of 1’s.
class Program_11 {
public static void main(String[] args) {
// creating a 6X6 matrix
int[][] matrix = new int[6][6];
for (int i = 0; i < matrix.length; i++) {
for (int j = 0; j < matrix[i].length; j++) {
matrix[i][j] = (int) (Math.random() * 2);
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}
// Display whether every row and columns have odd number of 1s
System.out.println("Envery row" + (isRowsOdd1s(matrix) ? " " : " does not " + "have an odd number of 1s"));
System.out.println("Envery row" + (isColumnOdd1s(matrix) ? " " : " does not " + "have an odd number of 1s"));
}
// isRowsOdd1s implementation
public static boolean isRowsOdd1s(int m[][]) {
int count = 0;
for (int i = 0; i < m.length; i++) {
for (int j = 0; j < m[i].length; j++) {
if (m[i][j] == 1)
count++;
}
if (count % 2 == 0)
return false;
}
return true;
}
// isColumnOdd1s implementation
public static boolean isColumnOdd1s(int m[][]) {
int count = 0;
for (int i = 0; i < m.length; i++) {
for (int j = 0; j < m[i].length; j++) {
if (m[j][i] == 1)
count++;
}
if (count % 2 == 0)
return false;
}
return true;
}
}
