以下代码出错![错误发生] [1]
import java.sql.*;
public class DBConnect{
public static void main(String a[]) throws SQLException{
// *package oracle.jdbc.driver does not exist*
Driver d=new oracle.jdbc.driver.OracleDriver();
DriverManager.registerDriver(d);
System.out.println("Driver is registered");
}
}
我想要打印文本没有逗号.
<html>
<head>
<title>Reverse</title>
</head>
<body>
<form name="rev">
Enter the string : <input type="text" name="str"/>
<input type="button" value="click" onclick="rev1()" /><br>
reverse of given string : <input type="text" name="res"/>
</form>
<script type="text/JavaScript">
function rev1(){
var a=rev.str.value;
var b=[];
var i,j=0;
for(i=a.length-1;i>=0;i--){
b[j]=a[i];
j++
}
//rev.res.value=b;
alert(b);
}
</script>
</body>
</html>
如果我输入输入,因为abc我得到输出c,b,a,但我想要它cba.
