本文整理了Java中java.lang.Boolean.equals()方法的一些代码示例，展示了Boolean.equals()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Boolean.equals()方法的具体详情如下：
包路径：java.lang.Boolean
类名称：Boolean
方法名：equals

Boolean.equals介绍

[英]Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must be an instance of Boolean and have the same boolean value as this object.
[中]将此实例与指定的对象进行比较，并指示它们是否相等。若要相等，o必须是布尔的实例，并且具有与此对象相同的布尔值。

@Override
public boolean equals(Object o) {
  if (this == o) return true;
  if (o == null || getClass() != o.getClass()) return false;
  SQLDataTypeImpl dataType = (SQLDataTypeImpl) o;
  if (name != null ? !name.equals(dataType.name) : dataType.name != null) return false;
  if (arguments != null ? !arguments.equals(dataType.arguments) : dataType.arguments != null) return false;
  return withTimeZone != null ? withTimeZone.equals(dataType.withTimeZone) : dataType.withTimeZone == null;
}
