Format string references missing argument

String sqlrightDate  =   " select state from right where user_id = '%s' and soft_code ='%s' 

and right_name = '%s'  " ;
    

String str  =  String.format(sqlrightDate, " 1 " ,"2" );
System.out.println(str);

 

错误的写法： String str  =  String.format(sqlrightDate, " 1 " );

 

描述：

 

 

Not enough arguments are passed to satisfy a placeholder in the format string. A runtime exception will 

occur when this statement is executed.
