如何讓用戶創建一個新的.txt文件，他們選擇在Java

Question

我試圖編寫的代碼有一個jTextField供用戶輸入一個字符串。用戶然後將點擊jButton創建文件。爲了創建文件，我想到了：從用戶處取得字符串輸入，並將其附加到文件創建方法中的.txt。下面的代碼顯示了這次不成功的嘗試：

String input; 
Scanner scan = new Scanner(System.in); 
input = scan; //This is totally wrong, but I'm not sure how to convert the scanner 

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {           
    final Formatter x; 
    try{ 

     x = new Formatter(input + ".txt"); 

    } catch(Exception e) { 
     System.out.println("Your code is bad. You should feel bad."); 
    } 
}   

private void jTextField1ActionPerformed(java.awt.event.ActionEvent evt) {            
    input = jTextField1.getText();   
}

沒關係，我找到了適合我的案例的最佳解決方案。不過謝謝！

final Formatter x; 
    try{ 

     x = new Formatter(jTextField1.getText() + ".txt"); 

    } catch(Exception e) { 
     System.out.println("Something went horribly wrong.."); 
    } 
}
