Java 與 C#

Java is a dynamic, secured and class based high level object oriented programming language developed by Oracle Corporation. On the other hand; C# is a .Net Framework object ori Corporation. On the other hand; C# is a 。 .

Java和C#都是通用的程式設計範式，或基本上被稱為命令式程式設計環境。而且這兩種語言都能夠提供一些高階結果作為輸出。

In a broad view there are many differences between these two OOPs −

• Java Runtime Environment旨在執行Java程式碼，而C#運行在CLR環境（公共語言執行時期）。

• Java和C#都是物件導向的程式語言。但是在特定的方式上，C#是一種功能和元件導向的強型別編碼語言。這種語言提供了多重重載的特性，而這是Java所沒有的。

• 這兩者的Array特性也不相同。對Java來說，Object是直接的專門化，而對C#來說，Array是系統的專門化。

Use of C# -

• Web app. Development

• #Windows application development.

• #Gaming application.

使用Java -

• Web項目，大數據應用程式

• Server-side programming

• Embedded systems

• Android應用程式

#Java和C#語言的工作原理：

Java

In a software designing environment, it is important to have a runtime platform. The runtime platform provides the access to main memory and other important features of a system to run a code.

Java執行環境（Java Runtime Environment）是一種基本的後端技術，它在Java建置程式碼和作業系統之間建立並建立通訊管道。簡單來說，JRE是一個執行時間工具，它提供了編寫Java程式碼並執行以獲得所需結果的所有資源。

There are two Java components −

• JDK – Java開發工具包

A collection of software development tools to develop an application using Java. You can get many JDK version in matching with its Java version. Like, Java SE needs JDK Java SE.

• JVM – Java Virtual Machine

JVM逐行執行Java程式碼。當Java應用程式運行時，開發人員配置設定。它還透過使用運行時檢查正在運行的Java應用程式的內部儲存。

C

#的中文翻譯為：

C

#Basically, the .NET build codes compile into a Microsoft Intermediate Language aka MSIL by using Just in Time (JIT) compiler. Clearly, the output will be a machine code (written by a set of class libraries and be a machine code (written by a set of class libraries) and class libraries) and class libraries beit it. produced by a machine processor.

The compiler and the CLR format the C# code to an executable code. Here we get an understanding complex machine environment in .NET. The executable codes can be saved as .exe and 。

A Java Code Algorithm:-

的中文翻譯為：

一個Java程式碼演算法：

• 第一步 - 在IDE中編寫原始程式碼。

• Step 2 − Put It Into The Compiler.

• 步驟3 - 將其轉換為字節碼。

• 步驟 4 − JVM（Windows，MacOS，Linux）。

• Step 5 − Converted Machine Code.

• #步驟 6 − 終止進程

A C# Code Algorithm:-

• Step 1 − Start.

• Step 2 − Select The Documents.

• #第三步 - 指令部分。

• Step 4 − Select Interface.

• #第五步 - 選擇課程。

• 第6步 - Main()方法宣告。

• 步驟 7 - 沒有頭文件，匯入 .dll 檔案。

• 第8步 - 輸入反射

Java程式碼的語法

public class Main {
   public static void main (String[] args) {
      System.out.println ("THE STATEMENT");
   }
}

Syntax

using System;

namespace Tutorialspoint {
  class Program{
      static void Main(string[] args){
         Console.WriteLine("Hello Student");    
    }
  }
}

The class using system declares the system namespace. The namespace organises the code as a container. Every line of the written code that runs, must be stay inside a class in C# language.

• 方法二：C#程式碼的通用範例。

一個Java程式碼的一般範例

Example 1

public class TableofMultiplication {
   public static void main(String[] args) {

      int num = 18, j = 1;
      while(j <= 20){
         System.out.printf("%d * %d = %d \n", num, j, num * j);j++;
      }
   }
}

輸出

18 * 2 = 36 
18 * 3 = 54 
18 * 4 = 72 
18 * 5 = 90 
18 * 6 = 108 
18 * 7 = 126 
18 * 8 = 144 
18 * 9 = 162 
18 * 10 = 180 
18 * 11 = 198 
18 * 12 = 216 
18 * 13 = 234 
18 * 14 = 252 
18 * 15 = 270 
18 * 16 = 288 
18 * 17 = 306 
18 * 18 = 324 
18 * 19 = 342 
18 * 20 = 360 

A General Example of A C# Code

#Example 1

using System;  
public class Exercise6  {  
   public static void Main() {
      int i,n;
   
	   Console.Write("\n\n");
       Console.Write("Display the multiplication table of the number:\n");
       Console.Write("-----------------------------------");
       Console.Write("\n\n");   

       Console.Write("Input the number you need to do multiplication: ");
       n= Convert.ToInt32(Console.ReadLine());   
       Console.Write("\n");
       for(i=1;i<=100;i++){
          Console.Write("{0} X {1} = {2} \n",n,i,n*i);
       }
   }
