set(string str)变量传参为int的问题

if (bo.getAnesthesiaMode() != null) {
if (bo.getAnesthesiaMode() != null) {
CodeMstrCoMpare codeMstrCoMpare = new CodeMstrCoMpare();
codeMstrCoMpare.setCompareCat(ICodeMstrCompareConst.AMD);
codeMstrCoMpare.setCompareAbbr(new String(bo.getAnesthesiaMode().split(ICodeMstrCompareConst.AMD)[1]));可以

codeMstrCoMpare.setCompareAbbr(bo.getAnesthesiaMode().split(ICodeMstrCompareConst.AMD)[1]);不报错，但是运行时，不能set成功

上面两行的区别？？？
List<CodeMstrCoMpare> list = crudDaoFactory.getCrudDao(CodeMstrCoMpare.class).findByExample(codeMstrCoMpare);
for(int i=0;i<list.size();i++){
if(list.get(i).getCodeCat() != ICodeMstrCompareConst.AMD){
list.remove(i);
}
}
if (ListUtil.isNotEmpty(list)){
CodeMstrCoMpare mstrCoMpare = list.get(0);
view.setAnesthesiaModeDesc(LanguageUtil.getInstance().getNormalDesc(language, mstrCoMpare.getCompareDesc(), mstrCoMpare.getCompareDescLang1()));
}
}
}
