Java Nested Tuples: List & Map Guide

In Java, you can use a List or Map to simulate nested tuple structures. Here’s how you can do it:

1. Use a list.

List<Object> tuple = new ArrayList<>();
tuple.add("value1"); // 添加元素到元组中
tuple.add("value2");
List<Object> nestedTuple = new ArrayList<>();
nestedTuple.add("nestedValue1"); // 添加元素到嵌套的元组中
nestedTuple.add("nestedValue2");
tuple.add(nestedTuple); // 将嵌套的元组添加到主元组中

1. Utilizing a map:

Map<String, Object> tuple = new HashMap<>();
tuple.put("key1", "value1"); // 添加键值对到元组中
tuple.put("key2", "value2");
Map<String, Object> nestedTuple = new HashMap<>();
nestedTuple.put("nestedKey1", "nestedValue1"); // 添加键值对到嵌套的元组中
nestedTuple.put("nestedKey2", "nestedValue2");
tuple.put("nestedTuple", nestedTuple); // 将嵌套的元组添加到主元组中

In this way, nested structures of tuples can be achieved. Values in the tuple can be accessed using either an index or a key.
