关于简单的JAVA降序问题

void sorting (){
<br>while(v.size() !=0) {
<br>String printLine = (String)(v.elementAt(0));
<br>int linenumber = 0;
<br>for(int ctr = 1; ctr &lt; v.size(); ctr++) {
<br>if((String) v.elementAt(ctr)).compareTo(printLine) &gt;0){
<br>printLine = (String) v.elementAt(ctr);
<br>linenumber = ctr ;  //这个是什么意思我不明白方这里;
<br>}
<br>}
<br>System.out.println(printLine);
<br>v.remove(linenumber);//这个不明白解释下
<br>}
<br>}
