String indexers treat strings as:
-
binary code
-
1 to string Length
-
arrays of characters
-
a character
To solve this question, the user needs to know the concept of string indexers.
String indexers treat strings as arrays of characters, where each character in the string is assigned an index value based on its position.
Option A is incorrect because string indexers do not treat strings as binary code.
Option B is incorrect because the index values assigned to characters in a string do not start from 1 and go up to the length of the string. They start from 0 and go up to length-1.
Option C is correct because string indexers treat strings as arrays of characters.
Option D is incorrect because a string is made up of multiple characters, not just one.
Therefore, the correct answer is: C. arrays of characters.
-
finds the first occurrence of each letter in the string
-
searches for the first occurrence of any of the characters in the string
-
will search for the first occurrence of the sequence of characters
-
generates an error
Concatenating with strings are done with:
-
reserved words
-
method calls
-
operator overloading

If two StringBuilder objects contain the same string then
-
they represent the same meory location
-
the are two different objects
-
if one changes, so will the other
-
None of the above
AI Explanation
To answer this question, you need to understand how StringBuilder objects work.
StringBuilder objects in Java are mutable, which means their values can be changed. When you create a StringBuilder object and assign it a specific string, you can modify the content of that object without creating a new object.
Now, let's go through each option to understand why it is correct or incorrect:
Option A) They represent the same memory location - This option is incorrect. StringBuilder objects are separate objects that can have the same content but are stored in different memory locations.
Option B) They are two different objects - This option is correct. If two StringBuilder objects contain the same string, they are still considered as separate objects. They have their own memory locations and can be modified independently.
Option C) If one changes, so will the other - This option is incorrect. If you modify the content of one StringBuilder object, it will not affect the other StringBuilder object, even if they contain the same string.
Option D) None of the above - This option is incorrect. Option B is the correct answer because StringBuilder objects with the same string content are still separate objects.
Therefore, the correct answer is B) They are two different objects.
The proper way to convert a string to all lowercase is:
-
String = string.ToLower(string);
-
ToLower(string);
-
string.ToLower();
-
string.ToLower(string);
How many levels of compilation happens in .NET Framework
-
One
-
Two
-
Three
AI Explanation
To answer this question, we need to understand the compilation process in the .NET Framework.
The .NET Framework uses a two-step compilation process.
The first step is the compilation of source code into an intermediate language (IL) known as Microsoft Intermediate Language (MSIL) or Common Intermediate Language (CIL). This step is performed by the compiler, which converts the source code into IL instructions.
The second step is the Just-In-Time (JIT) compilation, which occurs at runtime. The IL code is compiled into machine code specific to the target platform. This compilation is performed by the Common Language Runtime (CLR), which is responsible for executing .NET applications.
Therefore, the correct answer is B) Two, as there are two levels of compilation in the .NET Framework.
Most of the underlying integration of .NET is done through XML
-
True
-
False
AI Explanation
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) True - This option is correct. In the .NET framework, XML is commonly used for various purposes, including configuration files, data exchange, and serialization. XML is used extensively for integration purposes in .NET applications.
Option B) False - This option is incorrect. XML is indeed used for the underlying integration of .NET.
The correct answer is A) True. This option is correct because XML is widely used for integration in the .NET framework.
An Assemblyinfo file in a VB.NET project will have blank as file extesion.
-
.config
-
.vb
-
.cs
AI Explanation
To answer this question, we need to understand the purpose of an Assemblyinfo file in a VB.NET project and the file extension it typically has.
The Assemblyinfo file is a metadata file that contains information about an assembly, such as its version number, copyright information, and other assembly attributes. This file is automatically generated when you create a new VB.NET project.
In a VB.NET project, the Assemblyinfo file has the file extension ".vb". This file contains VB.NET code that specifies the assembly attributes for the project.
Let's go through each option to understand why it is correct or incorrect:
Option A) .config - This option is incorrect because the .config file is used for configuration settings and is not specific to the Assemblyinfo file.
Option B) .vb - This option is correct because the Assemblyinfo file in a VB.NET project has the file extension ".vb". This file contains the assembly attributes in VB.NET code.
Option C) .cs - This option is incorrect because the .cs file extension is used for C# source code files, not VB.NET Assemblyinfo files.
The correct answer is Option B. The Assemblyinfo file in a VB.NET project will have the file extension ".vb" because it contains VB.NET code for assembly attributes.
