public class Apple {
    private String name;
    private Integer price;
}
@Data

@Builder
public class Watermelon {
    private String name;
    private Integer price;
}

对象

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Fruit {
    private Apple apple;
    private Watermelon watermelon;
}
    private Fruit object() {
        return Fruit.builder()
                .apple(Apple.builder().name("苹果").price(20).build())
                .watermelon(Watermelon.builder().name("西瓜").price(25).build())
                .build();
    }

Map

    private Map<String, Object> map() {
        HashMap<String, Object> map = new HashMap<>();
        map.put("apple", Apple.builder().name("苹果").price(20).build());
        map.put("watermelon", Watermelon.builder().name("西瓜").price(25).build());
        return map;
    }

Pair

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.12.0</version>
        </dependency>
	private Pair<Apple, Watermelon> pair() {
        return ImmutablePair.of(Apple.builder().name("苹果").price(20).build(), Watermelon.builder().name("西瓜").price(25).build());
    }

Tuple2

        <dependency>
            <groupId>io.vavr</groupId>
            <artifactId>vavr</artifactId>
            <version>0.10.4</version>
        </dependency>
	private Tuple2<Apple, Watermelon> Tuple2() {
        return Tuple.of(Apple.builder().name("苹果").price(20).build(), Watermelon.builder().name("西瓜").price(25).build());
    }
