Java字符串处理

java判断字符串包含某个字符段

1. 用indexOf()方法

     String str = "1234567";

     }

2. 用repalce()方法

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

   String s1 = "abc";
   String s2 = "1111abcdefe"; 

   if(s2.contains(s1)){
    System.out.println("s2包含了s1");    //删掉s1
    s2 = s2.replace(s2.substring(s2.indexOf(s1), s2.length()), "");
    System.out.println(s2);
   }else{
    System.out.println("s2不包含s1");
   }
  }
}
