properties.forEach方法是用于遍历Properties对象中的所有键值对的方法。它接受一个lambda表达式作为参数,该lambda表达式定义了对每个键值对的操作。在给定的代码示例中,使用properties.forEach方法来打印Properties对象中的每个键值对。具体的实现如下:
properties.forEach((key, value) -> {
System.out.println(key + " = " + value);
});
这段代码将会打印出Properties对象中的每个键值对,以"键 = 值"的形式输出到控制台。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
