public class PrintASCII {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
//定义输出流
OutputStream fileOutputStream = new FileOutputStream("1.txt");
//ASCII从33到126之间的字符可以打印
int start=33;
int end=126;
int total=94;
int s=start;
int real;
int count=0;
while(count<94) {
for(int i=s;i
real=(i<=end)?i:(i%(end+1)+start);
fileOutputStream.write(real);
}
fileOutputStream.write(13);
fileOutputStream.write(10);

count++;
}
//关闭输出流
fileOutputStream.close();
System.out.println("Print successfully!");
}
}
不过，由于write一个字节一个字节的去写，效率低下，通常我们会采用缓存来积累数据字节，等积累到缓存容量时在一起发送，因此我们使用write(byte[] data)或write(byte[] date,int offset,int length)通常比一次写入date数组中的一字节要快得多，例如，下面将上面的程序优化一下：
package date0802;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
/**
* 向文件中打印ASCII表

*/
public class PrintASCII {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
//定义输出流
OutputStream fileOutputStream = new FileOutputStream("1.txt");
//ASCII从33到126之间的字符可以打印
int start=33;
int end=126;
int total=94;
int s=start;
int real;
int count=0;
byte[] line=new byte[total+2];
int flag;
while(count<94) {
flag=0;
for(int i=s;i
real=(i<=end)?i:(i%(end+1)+start);
line[flag++]=(byte)real;
}
line[flag++]=(byte)13;
line[flag++]=(byte)10;
fileOutputStream.write(line);
s++;
count++;
}
//关闭输出流
fileOutputStream.close();
System.out.println("Print successfully!");
}
}
输出结果为：
