/**字符串的艘寻*/
import java.io.*;
public class A003{
public static void main(String[] args){
String AA = "我是小炳炳";
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));//声明从健盘输入
System.out.println("AA = " + AA);

String CB;
System.out.print("请输入 = ");
CB = br.readLine(); //从键盘输入
int index = 0;
for(int i = 0; i < CB.length();i++)

index = AA.indexOf(CB,index);

System.out.println("他在这个位置上 = " + index);
}

}

运行不了！

要try catch IO异常，或者throws出去

import java.io.*;

public class A003 {
	public static void main(String[] args) throws IOException {
		String AA = "我是小炳炳";
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));// 声明从健盘输入
		System.out.println("AA = " + AA);

		String CB;
		System.out.print("请输入 = ");
		CB = br.readLine(); // 从键盘输入
		int index = 0;
		for (int i = 0; i < CB.length(); i++)

			index = AA.indexOf(CB, index);

		System.out.println("他在这个位置上 = " + index);
	}

}
