Check for 'null' values

This static utility allows you to check for any arbitrary number of values, ensuring none of them are null.

/**
 * Validates that all values are set.
 *
 * @param values a varargs array of arguments
 */
public static void defenseNotNull(Object... values) {
 if (values == null) {
 throw new IllegalArgumentException("values is null");
 }
 for (int i = 0; i < values.length; i++) {
 Object value = values[i];
 if (value == null) {
 throw new IllegalArgumentException(String.format("values[%d] is null", i));
 }
 }
}
