在按钮事件中读取文本，给你个文本文件读写的小例子：



import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;

public class TestMain {

/**
* 构造方法
*/
public TestMain() {
try {
File file = new File("C:\\test.txt");
BufferedWriter write = new BufferedWriter(new FileWriter(file, true));
for(int i = 0; i < 10; i++){
write.write("写入行数：" + i + "\n");
write.flush();
}
write.close();

BufferedReader read = new BufferedReader(new FileReader(file));
String temp = "";
while((temp = read.readLine()) != null){
System.out.println(temp);
}
read.close();
} catch (Exception e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
new TestMain();
}

}
