when I was in the primary school ,I had a unforgetful thing between me and my teacher???通過java實現輸入每個單詞首字母，就可以找到這些單詞。思路大概是用string字符串，通過空格將文章分成一個個字符串，然后檢索其中首字母。?

?if(s.startsWith(keyword))
?++count;
?return?count;

String?str?=?"when?I?was?in?the?primary?school?,I?had?a?unforgetful?thing?between?me?and?my?teacher";
String[]?arr?=?str.split("\\s+,*");?
