修改属性文件的问题
那要怎么写属性文件呢
比如我想把username=yq1012
改写成username=www.javaweb.top


Java code
Properties   p=new   Properties();
FileInputStream   in=new   FileInputStream(file);
FileOutputStream   out=new   FileOutputStream(file);
p.load(in);
p.setProperty( "username ", "www.javaweb.top");
p.store(out, "hello ");
