In JAVA 1.5, can we have two overridden methods with different return types?

Serializable interface has two methods which MUST overridden when a class implemnts Serializable interface.

List mylist = new ArrayList(); mylist.add(5); If you compile this lines in JAVA 1.5 , it will give compilation error.

For Arrays & Collection, Sort order & search order need not to be SAME.

What will be the output?public static void main(String[] args) { for (int i=0;i<= 10;i++){if( i>6) break;}System.out.println(i);}
