There is an error in "String s=s1-s2 ";

Explanation:

In java programming, we can subtract subtract two strings variable with "-" operator. Java programming does not support an overload of the '-' operator. In java, we can use only "+" operator to append two strings variable. There is no such method to subtract strings in java. Therefore in the given code String s=s1-s2 will give an "bad operand type" error because we can not subtract one string variable from the second string variable.
