写一个程序统计输入字符串中以“,”分隔的各种单词出现的次数。例如：输入的字符串为“java,java,j2ee,ibm,j2ee,ibm,j2me,jav
public class Test3 { public static void main(String[] args) throws IOException { BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); //输出提示语 System.out.println("请输入字符串 附：字符串之间用,隔开"); //读取输入字符串 String temp=br.readLine(); Map maps = new HashMap(); String[] templist = temp.split(","); for(int i = 0 ; i < templist.length;i++){ //准备放map String t = templist; //判断key boolean is = maps.containsKey(t); if(is == true){ //++1 Integer vs = (Integer)maps.get(t); vs++; maps.put(t, vs); }else{ //放`1 maps.put(t, 1); } } System.out.println(maps); } }
