How to create classes and objects in JShell in Java 9?

JShell是在Java 9中发布的一种新的Java shell工具。它是第一个官方的REPL（Read-Evaluate-Print-Loop）应用程序。该工具有助于执行和评估简单的Java程序和逻辑，例如语句、循环、表达式等等。Java REPL在命令提示符下提供了一个简单的编程环境。它可以读取输入、评估它并打印输出。

在下面的示例中，我们可以使用命令提示符在JShell中创建一个类和对象。

示例

jshell> class Employee { ...> private String name; ...> Employee(String name) { ...> this.name=name; ...> } ...> String getName() { ...> return name; ...> } ...> void setName(String name) { ...> this.name=name; ...> } ...> } | created class Employee

示例

jshell> Employee emp = new Employee("Adithya") emp ==> Employee@4b952a2d jshell> emp.getName() $3 ==> "Adithya"
