Question

在执行期间，调用该方法，整数i在屏幕上显示为0。但是，for循环内部没有输出，表明for循环没有执行。我还用断点测试了它，并获得了相同的结果。任何帮助表示赞赏。

private void decrypt_btnActionPerformed(java.awt.event.ActionEvent evt) {
    int ciphertext_length = Ciphertext().length();
    String decrypted_char = "";
    int i = 0;

    System.out.println("increment" + i);    

    try {
        for (i = 0; i == ciphertext_length; i++) {

            System.out.println("test" + i);

            String cipher_current_char = getLetterAtIndex(Ciphertext(), i);
            int pos_char_in_alphabet = getIndexAtLetter(Alphabet(), cipher_current_char);

            decrypted_char = decrypted_char +
                getLetterAtIndex(Alphabet(), pos_char_in_alphabet - 5);

            status_label.setText(100 / i + "%");
        }
    } catch (Exception e) {
        e.getMessage();
    }

    plain_ta.setText(decrypted_char);
}

Answer 1

  for (i = 0; i==ciphertext_length; i++){

应该很可能是

  for (i = 0; i<ciphertext_length; i++){

Java simple for循环不会迭代
