OOP-JAVA Practical 23

• PPS(C)
• JAvA

• Aim: Write a generic method that returns the minimum elements in a two dimensional array.
• Code:

  public class practical23 {
      public static void main(String[] args) {
          Integer matrix[][]=new Integer[5][5];
          for (int i = 0; i < 5; i++) {
              for (int j = 0; j < 5; j++) {
                  matrix[i][j]= (int) (Math.random()*50);
                  System.out.format("%3d",matrix[i][j]);
              }
              System.out.println();
          }
          System.out.println("Minimum element : "+min(matrix));
      }
      private static <E extends Comparable <E>> Object min(E[][] matrix) {
          E min = matrix[0][0];
          for (int i = 0; i < matrix.length; i++) {
              for (int j = 0; j < matrix.length; j++) {
                 if (matrix[i][j].compareTo(min)<0) {
                     min=matrix[i][j];
                 } 
              }
          }
          return min;
      }
  }
