FileOutputStream的write()的用法

package Demo01_OutPutStream;
import java.io.FileOutputStream;
import java.io.IOException;




public class Demo02_OutPutStream {

	public static void main(String[] args) throws IOException {
		FileOutputStream fos = new FileOutputStream("C:\File\a.txt");
		fos.write(97);
		fos.write(98);
		fos.write(99);
		
		byte[] bytes1 = {67,68,69};//CDE
		fos.write(bytes1);
		
		//当字节数组前面为负数的时候，他会和后一个数匹配，生成中文，后面的正数则为ACCII表中的对应字符
		byte[] bytes2 = {-67,-68,-69,68,69};//郊籇E
		fos.write(bytes2);
		
		String s = "中文";
		byte[] bytes3 = s.getBytes();
		fos.write(bytes3);//中文
		
		
		
		fos.close();
	}
}
