String s2 = "ello";

String s = s1-s2;

java programming

Answer 1

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

Step-by-step 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.
