Java基础-----大字符串中查找小字符串出现的次数

package java基础;

import java.util.Scanner;

public class Demo6_StringMethod {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		String str = scan.nextLine();
		String findstr = scan.nextLine();
		int num = 0;
		while(str.indexOf(findstr) != -1) {
			num ++;
			str = str.substring(str.indexOf(findstr) + findstr.length());
		}
		
		System.out.println(num);
		
	}
}

运行结果如下：
