Answer 1

public class Char02 {
public static void main(String[] args) {
System.out.println("请输入");
Scanner input = new Scanner(System.in);
String inputString =input.next();
char[] chars = inputString.toCharArray();

    int bigCount = 0;
    int smallCount = 0;
    int numCount = 0;
    StringBuilder big = new StringBuilder();
    StringBuilder small = new StringBuilder();
    StringBuilder number = new StringBuilder();

    for(int i=0;i<chars.length;i++){
        if(chars[i]>='A'&&chars[i]<='Z'){
            bigCount++;
            big.append(chars[i]);
        } else if(chars[i]>='a'&&chars[i]<='z'){
            smallCount++;
            small.append(chars[i]);
        } else if(chars[i]>='0'&&chars[i]<'9'){
            numCount++;
            number.append(chars[i]);
        }
    }
    System.out.println("大写字母有"+bigCount+"个："+big);
    System.out.println("小写字母有"+smallCount+"个："+small);
    System.out.println("数字有"+numCount+"个："+number);
}

}
