java if else 控制语句
String s="你好";
ResultSet rs=operate.executeQuery("select * from table1 where keyword='"+s+"'");//在table1中找

if(rs.next()){
//在table1中找到了
System.out.println("找到了");
}else{
//如果在table1中没找到，在table2中找
rs=operate.executeQuery("select * from table2 where keyword='"+s+"'");
}else{
//如果在table2中没找到，在table3中找
rs=operate.executeQuery("select * from table3 where keyword ='"+s+"'");
}else{
//如果在table1和table2中都找不到
System.out.println("都找不到");
}
请问这个怎么改，不要说把查询语句拿出来，那面只是我的简化代码，查询语句是不能拿出来的 Java if else
[解决办法]
主要代码：

String s="你好";
String[] tableNames = String[]{"table1","table2","table3"};
//主调用方法
public void selectData(){
    for(String tableName : tableNames){
       ResultSet rs = getMyResult(tableName,s);
       if(rs != null)
            break;
    }
    
    if(rs != null)
         Sysotem.out.println("查询导数据....");
    else
         Sysotem.out.println("没有查询到数据...");
}

//查询方法
private ResultSet getMyResult(String tableName,param s){
     ResultSet rs=operate.executeQuery("select * from "+tableName+" where keyword='"+s+"'");
    if(rs.hashNext()){
        return rs;
    }else{
        return null;
    }

[解决办法]
String s="你好";
String zd="没找到"
ResultSet rs=operate.executeQuery("select * from table1 where keyword='"+s+"'");

if(rs.next()){
zd="在table1中找到";
}
rs=operate.executeQuery("select * from table2 where keyword='"+s+"'");
if(rs.next()){
zd="在table2中找到";
}
rs=operate.executeQuery("select * from table3 where keyword='"+s+"'");
if(rs.next()){
zd="在table3中找到";
}

System.out.println(zd);

}
