Java Methods Quiz

Defining Java Methods: What is a method in Java?

• A method in Java is a block of code that performs a specific task and is defined within a class.

• A method in Java is a type of data structure

• A method in Java is a type of variable

• A method in Java is a form of loop

Defining Java Methods: What is the purpose of a return type in a Java method?

• It specifies the type of value that the method will return.

• It controls the visibility of the method.

• It specifies the name of the method.

• It determines the number of parameters the method can accept.

Passing parameters to Java Methods: What are parameters in Java methods?

• Containers used to store the method's code

• Reserved keywords used to define the method's behavior

• Special characters used to indicate the method's return type

• Variables used to pass values to the method

Passing parameters to Java Methods: Explain the process of passing parameters to a Java method.

• You declare the parameters within the parentheses of the method declaration and provide the actual values when calling the method.

• You declare the parameters after the method declaration

• You declare the parameters within the body of the method

• You declare the parameters in a separate file

Passing parameters to Java Methods: What is the difference between actual parameters and formal parameters in Java?

• Actual parameters are the values listed in the method declaration, while formal parameters are the variables passed to a method during a method call.

• Actual parameters are the values passed to a method during a method declaration, while formal parameters are the variables listed in the method call.

• Actual parameters are the values passed to a method during a method call, while formal parameters are the variables listed in the method declaration.

• Actual parameters are the variables listed in the method declaration, while formal parameters are the values passed to a method during a method call.

Method overloading in Java: What is method overloading in Java?

• When a class has multiple methods with the same name but different parameters.

• When a class has only one method with different parameters

• When a class has no methods with the same name

• When a class has multiple methods with the same name and same parameters

Method overloading in Java: What are the rules for method overloading in Java?

• The return type must always be different

• The rules for method overloading in Java are that the methods must have the same name but different parameters, and the return type may or may not be different.

• The methods must have the same name and the same parameters

• The methods must have different names and different parameters

Local scope in Java methods: What is local scope in Java methods?

• Local scope in Java methods allows variables to be accessed globally

• Local scope in Java methods refers to variables declared outside of any method

• Variables declared within a method can only be accessed within that method.

• Variables declared within a method can be accessed from any other method

Local scope in Java methods: Explain the concept of local variables in Java methods.

• Local variables can be accessed from any method within the same class

• Local variables are accessible from any class within the same package

• Local variables are accessible globally within the Java program

• Local variables are only accessible within the method in which they are declared.

Local scope in Java methods: How is the scope of local variables determined in Java methods?

• By the block of code in which the variable is declared

• By the order in which the variables are declared

• By the name of the variable

• By the return type of the method
