1	+	## Splitting a String
2	+
3	+	into a list or array of strings.
4	+
5	+	Key differences:
6	+
7	+	- Python returns a list directly
8	+	- Java returns an array (String[]), which you can convert to List if needed
9	+	- Python uses split() with no argument to split by any whitespace
10	+	- Java requires explicit delimiter - use split("\\s+") for any whitespace
11	+
12	+	in Python
13	+
14	+
15	+	```python
16	+	# Basic split (by spaces)
17	+	text = "hello world python programming"
18	+	words = text.split()
19	+	# Result: ['hello', 'world', 'python', 'programming']
20	+
21	+	# Split by specific delimiter
22	+	data = "apple,banana,orange,grape"
23	+	fruits = data.split(',')
24	+	# Result: ['apple', 'banana', 'orange', 'grape']
25	+
26	+	# Split with limit
27	+	text = "one-two-three-four"
28	+	parts = text.split('-', 2) # Split only twice
29	+	# Result: ['one', 'two', 'three-four']
30	+	```
31	+
32	+	in Java
33	+
34	+	```java
35	+	// Basic split (by spaces)
36	+	String text = "hello world java programming";
37	+	String[] words = text.split(" ");
38	+	// Result: ["hello", "world", "java", "programming"]
39	+
40	+	// Split by specific delimiter
41	+	String data = "apple,banana,orange,grape";
42	+	String[] fruits = data.split(",");
43	+	// Result: ["apple", "banana", "orange", "grape"]
44	+
45	+	// Split with limit
46	+	String text = "one-two-three-four";
47	+	String[] parts = text.split("-", 3); // Split only 3 times
48	+	// Result: ["one", "two", "three-four"]
49	+
50	+	// Convert to List if needed
51	+	List<String> fruitList = Arrays.asList(fruits);
52	+	// Or for a mutable list:
53	+	List<String> fruitList = new ArrayList<>(Arrays.asList(fruits));
54	+	```
