输入包括1行字符串,以“.”结束,字符串中包含多个单词,单词之间以一个或多个空格隔开。
可能有多组测试数据,对于每组数据, 输出字符串中每个单词包含的字母的个数。
hello how are you.

使用String的split方法,用正则表达式空格分开成小的字符串数组
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
while(in.hasNext()) {
String str = in.nextLine();
String[] arr = str.split(" ");
for(int i = 0; i < arr.length; i++) {
if(i == arr.length - 1) {
System.out.print(arr[i].length() - 1);
}
else
System.out.print(arr[i].length() + " ");
}
}
}
}
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while (sc.hasNext()){
String str = sc.nextLine();
int temp = 0;
for (int i = 0; i < str.length(); i++){
if (str.charAt(i) != ' ' && str.charAt(i) != '.'){
temp++;
}
else if (str.charAt(i) == ' ' ){
System.out.print(temp + " ");
temp = 0;
continue;
}
else if (str.charAt(i) == '.'){
System.out.print(temp);
temp = 0;
break;
}
}
System.out.println();
}
}
}
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String str = scanner.nextLine();
String[] result = str.split("\\s+");
for (int i = 0,n = result.length; i < n; i++) {
if (i == n - 1) {
System.out.print(result[i].length() - 1);
} else {
System.out.print(result[i].length() + " ");
}
}
}
}
