What is the symbol that causes the computer to perform string concatenation?
neonofarm [45]

Answer: In java the symbol "+" operator is used to perform string concatenation.

Explanation:

String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.

An example of String concatenation is as follows:

int age = 10;

System.out.println("The boys age is " + age);

Output:

The boys age is 10.

here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.

Ben wants to create a Book class that has an instance variable serialNumber. Where should he declare the instance variable
MrMuchimi

Answer:

within the Book class but needs to also be outside of any methods.

Explanation:

If Ben is creating an entire Book class then the instance variable needs to be within the Book class but needs to also be outside of any methods. If Ben places the variable inside a method it can only be used by that method and therefore becomes an instance variable of that method and not the class. By creating it inside the class and outside the methods it can be used every single time a Book object is created. Therefore, creating an instance variable of serialNumber every time.
