Question

我想要输出没有空格的java程序，我的代码是 -

Source source1=new Source(new URL(sourceUrlString1));
List<Element> temp1 = source1.getElementById("main").getAllElementsByClass("grid_3 alpha");

                String line = temp1.toString();
                String temps = line.trim();//using this
                            String temps = line.replaceAll("\\s+","")// or this
                if(!temps.isEmpty())
                {
                sendResponse(resp, "Information for:"+searchWord+":" +temps);
                }

当我使用修剪时，它会在信息和。之间提供大量空间的输出 SATISH

Information for::[




SATISH


JHOTWARA (JAIPUR)

Party:CPI
S/o|D/o|W/o: Om Prakash
Age: 42

当我使用String temps = line.replaceAll("\\s+","");

时

它输出为：

Information for::[<divclass="grid_3alpha"style='background:khaki;'><h2class="main-title">SatishKumar<fontcolor=greensize=1>(Winner)
ELECTEDFROMBIHARLEGISLATIVEASSEMBLY
<divclass="grid_2alpha">Party:JD(U)<divclass="grid_2alpha">S/o|D/o|W/o:JagdishPrasad<divclass

Answer 1

String temps = line.replaceAll("\\s+"," ");

每次运行会留出一个空格。

Answer 2

修剪只会削减前导和尾随空格，另见here。我按照你的意愿做了同样的事情，我用的只是

String temps = line.replaceAll(" ","");

如何删除列表对象中的空格？
