代码语言:javascript复制2.从键盘上输入10个字符到数组中, 并将其转换为字符串,统计该字符串中大写字母、小写字母和其他字符的个数。
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
char[] chars=new char[5];
for (int i = 0; i < chars.length; i ) {
System.out.println("请输入一个字符:");
chars[i]= scanner.nextLine().charAt(0);
}
String s=String.valueOf(chars);
System.out.println(s);
int d=0,x=0,others=0;
for (int i = 0; i < chars.length; i ) {
if (chars[i]<='Z'&&chars[i]>='A'){
d ;
}else if (chars[i]<='z'&&chars[i]>='a'){
x ;
}else{
others ;
}
}
System.out.println("大写字母有" d "个。");
System.out.println("小写字母有" x "个。");
System.out.println("其他有" others "个。");
}
