Where is the error in this code sequence?

string s1 = "hello";

string s2 = "ello";

string s = s1-s2;

java programming

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.
