Question

我在同一java文件中有两个类文件。我该如何在def plot_stats_test(feature,label_rotation=False,horizontal_layout=True): temp = df_test_2[feature].value_counts() df1 = pd.DataFrame({feature: temp.index,'Количество клиентов': temp.values}) # Расчет доли target=1 в категории cat_perc = df_train_2[[feature, Target']].groupby([feature],as_index=False).mean() if(horizontal_layout): fig, (ax1, ax2) = plt.subplots(ncols=2, figsize=(12,6)) else: fig, (ax1, ax2) = plt.subplots(nrows=2, figsize=(12,14)) sns.set_color_codes("pastel") s = sns.barplot(ax=ax1, x = feature, y="Количество клиентов",data=df1) if(label_rotation): s.set_xticklabels(s.get_xticklabels(),rotation=90) plt.tick_params(axis='both', which='major', labelsize=12) s = sns.barplot(ax=ax2, x = feature, y='Target', data=cat_perc, order=cat_perc[feature]) if(label_rotation): s.set_xticklabels(s.get_xticklabels(),rotation=90) plt.ylabel('Доля продленных', fontsize=10) plt.tick_params(axis='both', which='major', labelsize=10) plt.show();类列表中同时调用它们？例如，我有两个类A和B，而Java文件名显然是testng.xml，其中A是类。如何从A.java

调用B类

您基本上会使用$符号来引用内部类。

假设您有一个示例，如下所示

package com.rationaleemotions.stackoverflow.qn53476365;

import org.testng.annotations.Test;

public class SampleClass {

  @Test
  public void testMethod() {
    System.err.println("Hello from SampleClass");
  }

  public static class InnerClass {

    @Test
    public void testMethod() {
      System.err.println("Hello from InnerClass");
    }
  }
}

您将在InnerClass文件中参考如下所示的testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="53476365_Suite" parallel="false" verbose="2">
    <test name="53476365_Test">
        <classes>
            <class name="com.rationaleemotions.stackoverflow.qn53476365.SampleClass"/>
            <class name="com.rationaleemotions.stackoverflow.qn53476365.SampleClass$InnerClass"/>
        </classes>
    </test>
</suite>

输出如下
