一道面试题 的正解 保证汉字不被截半个

publicclassTest
{
publicstaticvoidmain(String[]args){

Strings="我ABC汉DEF";

intlength=6;
Strings2=subString(s,length);
if(s.indexOf(s2)==-1){
s2=subString(s,length-1);
};
System.out.println("正确答案:"+s2.trim());
}

privatestaticStringsubString(Strings,intbl){
byte[]bytes=s.getBytes();
byte[]newbytes=newbyte[128];
for(inti=0;i<bl;i++){
byteb=bytes[i];
newbytes[i]=b;

}
returnnewString(newbytes);
}
