Code from recitation 8

1. Searching through a 2D array for a particular element.

     ArraySearch.java 

  1  
  2  public class ArraySearch {
  3   public static void main(String[] args) {
  4    String[][] str = {
  5     { "a", "b", "c", "d" },
  6     { "e", "f", "g", "h" }
  7    };
  8  
  9    String goal = "c";
 10    
 11    boolean error = true;
 12    for (int i=0; i<str.length; i++) {
 13     for (int j=0; j<str[i].length; j++) {
 14      if (str[i][j].equals(goal)) {
 15       error = false;
 16       System.out.println("row = " + i);
 17       System.out.println("col = " + j);
 18       break;
 19      }
 20     }
 21     if (!error) {
 22      break;
 23     }
 24    }
 25    if (error) {
 26     System.out.println("Error");
 27    }
 28   }
 29  }
 30

2. Running out of memory

     OutOfMemory.java 

  1  
  2  public class OutOfMemory {
  3   public static void main(String[] args) {
  4    int[] x = new int[1];
  5    while (true) {
  6     int y = x.length;
  7     y = y * 2;
  8     System.out.println(y);
  9     x = new int[y];
 10    }
 11   }
 12  }
