A ____ checks a value, and based on the result performs one of two actions.

short-circuit structure

block structure

decision structure

sequence structure

Object-oriented programmers use the term ____ when a child class contains a field or method that has the same name as one in the parent class.

parent friendly

override

ambiguous

out of scope

When creating a for loop, which statement will correctly initialize more than one variable?

for(a=1, b=2)

for a=1, b=2

for(a=1; b=2)

for(a = 1&& b = 2)

Altering a variable within both a for statement and within the block it controls can produce errors that are difficult to find.

True

False

When a value is returned from a method, you are required to use the value when the method is called.

True

False

____ are also called modules, methods, functions, and subroutines. Java programmers most frequently use the term “method.”

Procedures

Applications

Classes

Calls

Which of the following is NOT a component of a variable declaration statement?

ending semicolon

symbolic constant

data type identifier

variable name

Solution

1. Decision structure checks a value, and based on the result performs one of two actions.Decision structure decides which statement will get executed and when based on some condition.

2.Object-oriented programmers use the term Override when a child class contains a field or method that has the same name as one in the parent class.Overriding means to inherit properties of parent class and add its own functionality. overriding is used to add further functionality to existing functionality.

3.When creating a for loop, following statement will correctly initialize more than one variable

for(a=1, b=2)

it is predifened syntax for programming languages.

4.True.

Altering a variable within both a for statement and within the block it controls can produce errors that are difficult to find as it might lead to usage of wrong value while program execution.

5. True When a value is returned from a method, you are required to use the value when the method is called.

we need to catch the returned value in some variable while calling that function otherwise it will throw compilation error.

6 Procedures are also called modules, methods, functions, and subroutines. Java programmers most frequently use the term “method.” Procedures contains functionality added by user

7.symbolic constant is NOT a component of a variable declaration statement

variable declaration : int a= 10;-->semicolon

a--> variable name

int--->datatype identifier
