Linux下C++调用Java简单实例（jni）

假设工作目录为/home

1. Java端

1)  mkdir leixf && cd leixf

2) 创建SubClass.java文件，内容如下：

package leixf;

public class SubClass {
private String name = null;
public SubClass(String name){
this.name = name;
}

public void say(){
System.out.println("Hello " + this.name);
}
}

3) 创建Demo.java文件，内容如下：

package leixf;

public class Demo {


public static void main(String[] args) {
new Demo("Xiaofeng").myCall();
}


public Demo(){
//System.out.println("in default constructor");
this.name = "default";
//System.out.println("name is " + this.name);
}

private String name = null;
public Demo(String name){
//System.out.println("in special constructor");
this.name = name;
//System.out.println("name is " + t
