Answer 1

import java.util.Scanner;

public class Shangji {
public static void main(String[] args) {

    int count = 0;
    Scanner input = new Scanner(System.in);
    System.out.println("请输入一个字符串:");
    String inputs = input.next();
    System.out.println("请输入要查找的字符:");
    String word = input.next();
    System.out.println("字符串为:" + inputs);

    for (int i = 0; i <= inputs.length() - 1; i++) {
        String g = inputs.substring(i, i + 1);
        if (g.equals(word)) {
            count++;
        }
    }
    System.out.print("包含"+count+"个"+word);

}
