怎么把这个程序的结果分三行输出?

[summit128]

class HexRead{
String[] input={"000A110D1D260219",
"78700F1318141E0C",
"6A197D45B0FFFFFF"
};

public static void main(String[] arg){
HexRead hex=new HexRead();
for(int i=0;i<hex.input.length;i++)
hex.readLine(hex.input[i]);
}

void readLine(String code){
try{
for(int j=0;j+1<code.length();j+=2){
String sub=code.substring(j,j+2);
int num=Integer.parseInt(sub,16);
if(num==255)
return;
System.out.println(num);
}
}finally{
System.out.println("**");
}
return;
}
}

没整明白什么意思。

[fish2mini]

for(int j=0;j+1<code.length();j+=2)
{
String sub=code.substring(j,j+2);
int num=Integer.parseInt(sub,16);
if(num==255);
return;
System.out.print(num);// println--->print
}
//add this code
System.out.println();
