C# 与 JAVA 常见代码对照表

C#与 JAVA 常见代码对照表在软件开发中，C# 和 JAVA 是两种非常流行的编程语言。它们都有着强大的功能和丰富的库，但是在语法和用法上有一些不同。下面是一些常见的代码对照表，帮助你更好地理解两种语言之间的差异。

1. 变量声明和初始化C#:

csharpint num =10;
string name = "John";

javaint num =10;
String name = "John";

csharpif (num >0)
{
 Console.WriteLine("Number is positive");
}
else if (num <0)
{
 Console.WriteLine("Number is negative");
}
else{
 Console.WriteLine("Number is zero");
}

javaif (num >0)
{
 System.out.println("Number is positive");
}
else if (num <0)
{
 System.out.println("Number is negative");
}
else{
 System.out.println("Number is zero");
}

csharpfor (int i =0; i <5; i++)
{
 Console.WriteLine(i);
}

javafor (int i =0; i <5; i++)
{
 System.out.println(i);
}

csharppublic void SayHello(string name)
{
 Console.WriteLine("Hello, " + name);
}

javapublic void sayHello(String name)
{
 System.out.println("Hello, " + name);
}

csharppublic class Person{
 public string Name { get; set; }
 public int Age { get; set; }
 public Person(string name, int age)
 {
 Name = name;
 Age = age;
 }
}

javapublic class Person{
 private String name;
 private int age;
 public Person(String name, int age)
 {
 this.name = name;
 this.age = age;
 }
}
