Computer History

100

Ada Lovelace was the first __________.

Computer Programmer

200

Creating the first high level language is credited to famouse programmer ________. 

Grace Murray Hopper

300

Charles Babbage's Differential Engine and ENIAC had little in common except that they were both created to _________.

Calculate Mathematical Equations for the Military

400

The first computer (ENIAC) was programmed using ________.

Switches that represented binary

500

Charles Babbage's differential engine was inspired by:

A French industrial loom that used cards to control the pattern of the threads

Input Basics

100

What class is used to read from the keyboard?

Scanner

200

What function is used to read a String value from the user?

nextLine()

300

Can you print a user-entered value simultaneously while you read the value from the keyboard?

NO.

400

Which of these is NOT a Scanner library call (to the best of your knowledge):

nextBoolean()

nextDouble()

nextChar()

nextChar()

500

//Will this code print the user entered value?

Scanner kb = new Scanner(System.in);

S.O.P("Who is your daddy and what does he do: ")

kb.nextLine();

NO.

Data Types

100

What is a Data Type?

The kind of information stored in a variable.

200

Name a non-primitive data type.

String, Scanner, Random

300

What's the difference between int and double?

int - whole number

double - decimal

400

An error with Data Types is considered a ______ Error.

Syntax

500

A String is made of ________.

chars

Parts of Coding Language

100

What is the correct symbol for a comment?

// and/or /* */

200

This is a direct representation of data in the code.

Literal

300

This refers to a specific place in computer memory and the current value stored there.

Variable

400

These have specific, unchangeable meaning in the computer language.

Key Word

500

This is code that someone else wrote that you can use.

Library Call

Where's the Error?!

100

System.out.printl("Hello!");

println

200

int x = 4.5;

4.5 is not a whole number

300

boolean isTrue = kb.nextLine();

should be nextBoolean()

400

Scanner kb = new Scanner();

Scanner(System.in);

500

System.out.println("Math.pow(2,2)");

Logic Error

How Do I Code That?

100

Print "Hello World!"

System.out.println("Hello World!");

200

Declare and Initialize a String Variable called x to the literal text value hello

String x = "hello";

300

Declare a boolean variable named canWin

boolean canWin;

400

Create the Scanner object kb

Scanner kb = new Scanner(System.in);

500

Write the import statement needed for the Scanner and Random libraries

import java.util.*;
