String string = "string";
`String` 是一种类型 - [java.lang.String][1]，而 `string` 只是一个变量的名称。这是它们可以用在不同场景的主要区别。
请查阅文档：
- [变量][2]
- [字符串][3]
- [什么是对象？][4]

英文:
String string = "string";
String is a type - java.lang.String and string is just a name of variable. This is the main difference which leads us to where each can be used.

String是Java中的一个类。它被几乎所有人用来存储一系列字符。string是一种'数据类型'。大多数人通常会使用str或string作为String类类型的变量名。
例如："abc"是一种字符串类型，但是是String类的一个'对象'。
英文:
String is a class in Java. It is used by almost everyone, to store a bunch of characters. string is a type of 'data type'. Most people would generally use str or string for a variable name of the type of class String
For example: "abc" is a type of string, but an 'object' of the String class.

在Java中，String是一个类名（其完整名称为java.lang.String）。由于java.lang包会被自动导入，您可以如下使用String类：
String myString = "this is my string!";
在Java中没有保留的string关键字，但您可以创建一个以此命名的变量：
String string = "this is a string!";
英文:
In Java, String is a class name (its full name is java.lang.String). As the java.lang package is imported automatically, you can use String class as follows:
String myString = "this is my string!";
There's no reserved string word in Java, but you can create a variable with that name:
String string = "this is a string!";
