parseInt - Spot the Errors

Goal:

Write the following snippets on the whiteboard and ask students to fix the errors.

Steps:

1. Have students take turns and tell them to only fix ONE mistake so everyone gets plenty of turns.
2. Ask students not to erase the original code, just put a line through an error and write their suggestion above. That way if the fix is not correct, another student can still see the original.
   
   Snippet 1:

   String repeat = JOptionPain.showInput("How many students are there?");
   
   int numRepeats = Integer.parse(repeat);
   
   for(int i; i > repeat; i++) {
         System.print.out (student + numRepeats) 
   }
   

   
   
   Snippet 2:

   String answer = JOptionPane.showInputDialog("How many bottles?" );
   
   int bottles = integer.passInt(bottles);
   
   for ( i=bottles; i < 0; i++ ) {
         JOptionPane.showMessageDialog(nil, i "green bottles hanging on the wall/n Crash!!!!" );
   }
   
   JOptionPane.showMassageDialog(nil, "There's a lot of broken glass out here!" );
