输入一行字符,分别统计出其中英文字母、空格、数字和其它字符的个数。
public class Example07 {
public static void main(String[] args) {
String s = "Hello World! BeiJing AoYun 2008。";
number(s);
}
public static void number(String s) {
int digital = 0;
int character = 0;
int other = 0;
int blank = 0;
char[] ch = s.toCharArray();
for (int i = 0; i < ch.length; i++) {
if (ch[i] >= ‘0‘ && ch[i] <= ‘9‘) {
digital++;
} else if ((ch[i] >= ‘a‘ && ch[i] <= ‘z‘) || ch[i] > ‘A‘
&& ch[i] <= ‘Z‘) {
character++;
} else if (ch[i] == ‘ ‘) {
blank++;
} else {
other++;
}
}
System.out.println("要测试的字符串为: " + s);
System.out.println("数字个数: " + digital + "\n英文字母个数: " + character
+ "\n空格个数: " + blank + "\n其他字符个数:" + other);
}
}
