# hello-vm

一个只支持三个指令的超级mini的虚拟机

# 用法

```java

package org.slince.hellovm;

import java.util.List;

public class Main {

    public static void main(String[] args) {

        VirtualMachine vm = new VirtualMachine();

        List instructions = List.of(

                new VirtualMachine.Instruction("push", 1), // 常量入栈

                new VirtualMachine.Instruction("push", 2), // 常量入栈

                new VirtualMachine.Instruction("add", null), // 栈上加法

                new VirtualMachine.Instruction("push", 5), // 入栈

                new VirtualMachine.Instruction("sub", null) // 栈上减法

        );

        // 以上指令相当于 1 + 2 - 5 ； 输出-2

        System.out.println(vm.execute(instructions));

    }

}

```

这很酷！
