private int byteNum;

public TestSplitString(String str, int byteNum) { this.str = str;

this.byteNum = byteNum;

} //截取字符串的函数(只要写出这个函数就可以) public void splitString() { byte bt[] = str.getBytes();

System.out.println( Length of this String ===>

+ bt.length);

if (byteNum >

1) { if (bt[byteNum] <

0) { String substrx = new String(bt, 0, --byteNum);

System.out.println(substrx);

} else { String substrex = new String(bt, 0, byteNum);

System.out.println(substrex);

} } else { if (byteNum == 1) { if (bt[byteNum] <

0) { String substr1 = new String(bt, 0, ++byteNum);

System.out.println(substr1);

} else { String subStr2 = new String(bt, 0, byteNum);

System.out.println(subStr2);

} } else { System.out.println( 输入错误!!!请输入大于零的整数: );

} } } //程序内测试方法 public static void main(String[] args) { TestSplitString tss = new TestSplitString( David大卫David , 8);

tss.splitString();

} }

2、public class Test3 { public static void main(String[] args) throws IOException { String name, phoneNumber;

BufferedReader reader1 = new BufferedReader(new InputStreamReader(System.in));

FileWriter file = new FileWriter( E:/F1.txt );

while (true) { System.out.println( Please input Name: );

name = reader1.readLine();

if (!name.equals( done )) { file.write(name);

file.write( );

} else break;

System.out.println( Please input PhoneNumber: );

phoneNumber = reader1.readLi........
