public class myFirstClass {
    public static void main(string[] args) {
        System.out.println("hello eclipse");
    }
}

should be

应该是

public class myFirstClass {
    public static void main(String[] args) { 
        System.out.println("hello eclipse");
    }
}

Use String not string.

使用字符串而不是字符串。

public static void main(String[] args) { System.out.println("hello eclipse"); }

Java classes are case sensitive. String is the class you need.

Java类是区分大小写的。字符串是您需要的类。

"cannot be resolved to a type" means that the compiler has decided that, according to the syntax of the language, what it found at this place in the code has to be type, which means either a class, an interface, or a primitive tpye, but cannot find the definition of any type with that name.

“不能解决一个类型”意味着编译器已经决定,根据语言的语法,它在这个地方找到代码中的类型,这意味着一个类,接口,或原始打字,但无法找到任何类型的定义与这个名字。

In this case, "string" cannot be resolved because there is no such type - Java is case sensitive, and the class is named String. There is an extremely strong convention for class names to start with an uppercase letter. The only lowercase types you'll normally encounter are the primitive types like int and boolean.

在这种情况下，“string”不能被解析，因为没有这样的类型—Java是区分大小写的，类是命名字符串。对于类名，有一种非常强的约定以大写字母开头。您通常会遇到的唯一的小写类型是int和boolean等基本类型。

When you get this error the typical reasons are:

当你得到这个错误的时候，典型的原因是:

• you mistyped the name of the type
• 你把字体的名字弄错了。
• or the package in the import statement is wrong
• 或者导入语句中的包是错误的。
• or you have a problem with the classpath.
• 或者你对类路径有问题。

As per the Java language Specification the signature of main() method takes a parameter of String array. As Java is case sensitive and there is no such type/class called "string" thus it is giving you the said error. We have "String" as a class in java which should be present over there as "String[] args".

根据Java语言规范，main()方法的签名采用字符串数组的参数。由于Java是区分大小写的，所以没有所谓的“string”类型/类，因此它给出了所述错误。我们将“String”作为java中的一个类，它应该作为“String[] args”出现在那里。
