Question

Differentiate between the function of + operator when used with integer and string value

Answer 1

Explanation:

+ operator when used between the 2 or more strings  concatenates them all, for example:

String str = "a" + "sample"+"concatenation";

in output the value of str would be "a sample concatenation"

and when + operator is used between the integer variables, add the values of them, for example:

int val  = 5+6+7;

in output the value of val would be 18.
