[英]java coding in netbeans
The following code written in netbeans it shows error as cannot find length()
method and invert if.im new to netbeans. 以下用netbeans编写的代码显示错误,因为找不到length()
方法并反转了netbeans新的if.im。 please correct my code.thanks in advance. 请更正我的代码。谢谢。
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
if(jTextField1.getText().trim().length() == 0 && jPasswordField1.getPassword().length() == 0)
getPassword()
returns char[]
so use .length
field getPassword()
返回char[]
因此请使用.length
字段
jPasswordField1.getPassword().length
