但是请注意，，我们在使用的时候因为是要在android studio上面使用的所以需要修改

 
    class="dp-j" style="font-family:Consolas,"Courier New",Courier,mono,serif; white-space:pre-wrap; padding:0px; list-style-position:initial; border-top:none; border-right:1px solid rgb(231,229,220); border-bottom:none; border-left:none; color:rgb(92,92,92); margin:0px 0px 1px 45px!important">

  2. class="alt" style="margin-left:40px; list-style:decimal; border-top:none; border-right:none; border-bottom:none; border-left:3px solid rgb(108,226,108); color:inherit; line-height:18px; margin-top:0px!important; margin-right:0px!important; margin-bottom:0px!important; padding:0px 3px 0px 10px!important">        System.out.println(class="class="tags" href="/tags/STRING.html" title=string>string" style="margin:0px; padding:0px; border:none; color:blue; background-color:inherit">"请输出字符创");  
  3.         String   result=s.nextLine();  
  4. class="alt" style="margin-left:40px; list-style:decimal; border-top:none; border-right:none; border-bottom:none; border-left:3px solid rgb(108,226,108); color:inherit; line-height:18px; margin-top:0px!important; margin-right:0px!important; margin-bottom:0px!important; padding:0px 3px 0px 10px!important">        class="keyword" style="margin:0px; padding:0px; font-weight:bold; background-color:inherit; color:rgb(0,102,153); font-size:14px; word-wrap:normal; border:none">char x[]=result.toCharArray();  


修改后的主要是可以自己定义的字符串
String s="daold  dkajoe 39 sdied zhogn 中的.dk dodkdkeo o ";
char x[]=s.toCharArray();
