Q) Explain about “+” operator in java ?

A)

->it is a binary operator i.e., it acts upon two operands.

->it is the only operator that is overloaded in java.

->it acts both as arithmetic addition operator and string concatenation operator. Is both are operands are of numerical type; it acts as arithmetic addition operator. If at least one of the operands is a string it acts as string concatenation operator.

Note: operator overloading feature is not there in java

Ex: int a=10;

Int b= 30;

Int c= a+b;

System.out.println(“the sum  :”+a+b);

here o/p is sum is 1030

System.out.println(“the sum  :”+(a+b));

Here o/p is 40

->in c++ program has flexibility. The operator functionality can be overloading in many cases.

->in java “+“is the operator implementing polymorphism (as “+” is behaving different in different situations).
