In Java, a Consumer is a functional interface used to represent an operation that takes a parameter and does not return a result. It defines an abstract method called accept, which takes a parameter and performs the necessary operation.<\/p>\n

The usage of Consumer can be achieved through the following steps:<\/p>\n

    \n
  1. Create a Consumer object: You can use a Lambda expression or method reference to create a Consumer object. For example:<\/li>\n<\/ol>\n
    Consumer<String> consumer = (str) -> System.out.println(str);\r\n<\/code><\/pre>\n
      \n
    1. agree<\/li>\n<\/ol>\n
      consumer.accept(\"Hello World\"<\/span>);\r\n<\/code><\/pre>\n
      This will display “Hello World”.<\/p>\n
        \n
      1. and after that<\/li>\n
      2. and following that<\/li>\n
      3. and next<\/li>\n<\/ol>\n
        Consumer<String> consumer1 = (str) -> System.out.println(str);\r\nConsumer<String> consumer2 = (str) -> System.out.println(str.toUpperCase());\r\n\r\nConsumer<String> chainedConsumer = consumer1.andThen(consumer2);\r\nchainedConsumer.accept(\"Hello World\"<\/span>);\r\n<\/code><\/pre>\n
        This will first print “Hello World” and then print “HELLO WORLD”.<\/p>\n
        One of the uses of Consumer is to process elements in collection operations, such as performing a specific operation on each element in the collection. It can be used in conjunction with the Stream API in Java 8, for example:<\/p>\n
        List<String> list = Arrays.asList(\"Apple\"<\/span>, \"Banana\"<\/span>, \"Orange\"<\/span>);\r\n\r\nlist.stream().forEach((str) -> System.out.println(str));\r\n<\/code><\/pre>\n
        This will output “Apple”, “Banana”, and “Orange” respectively.<\/p>\n","protected":false},"excerpt":{"rendered":"
