Default values

JVM gives the defalut values to instance variables but not to stack (method) variables. Only arrays are exception from this rule. If you initialize the array like int[] intArr = new int[10]; java gives zero (default value for int) to all elements of array and it does not depend whether intArr is local or method variable. Another example is Object[] objArray = new Object[10]; Inthis case all elements of array will be null.
