Checked Exceptions - Try-catch block

try {
  int[] b = new int[10];
  for ( int i = 0; i < b.length; i++) {
    int datum = System.in.read();
    if (datum  == -1) 
      break;
    b[i] = datum;
  }
}
catch (IOException e) {
  System.err.println("Couldn't read from System.in!");
}


		Checked Exceptions in a try-catch block Example The java.io.IOException is a checked exception, so you'll need to wrap all calls to this method in a try-catch block.
	try { int[] b = new int[10]; for ( int i = 0; i < b.length; i++) { int datum = System.in.read(); if (datum == -1) break; b[i] = datum; } } catch (IOException e) { System.err.println("Couldn't read from System.in!"); }
