仔细读题 （Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

while(input.hasNext()){

String str=input.nextLine();

String a[]=str.split("\\.");

String b[][]=new String[300][300];

for (int i =0; i<a.length; i++) {

b[i]=a[i].split(" ");

}

int count=0;

String c[]=new String[300];

int k[]=new int[300],max=0;

for (int i = 0; i <a.length; i++) {

for (int j = 0; j < b[i].length; j++) {

String ca=b[i][j].trim();

if(ca.contains(","))ca=ca.substring(0, ca.length()-1);

if(ca.equals(""))continue;

ca=ca.toUpperCase();

int m=check(ca,c);

if(m==-1){

c[count]=ca;

if(ca.length()>max)max=ca.length();

k[count]=1;

count++;

}

else{

k[m]++;

}

}

}

for (int i = 0; i < count; i++) {

    for (int j = 0; j <max-c[i].length(); j++) {

System.out.print(" ");

}

System.out.print(c[i]+":");

for (int j = 0; j <k[i]; j++) {

System.out.print("*");

}

System.out.println(k[i]);

}

}

}

private static int check(String s, String[] c) {

for (int i = 0; i <c.length; i++) {

if(s.equals(c[i])){

return i;

}

}

return -1;

}

}
