How to Split Strings Using the String Split Method in Java

When it comes to coding, splitting strings is a very frequent operation that developers often perform. In this article, we will focus on how to split strings using the `split()` method in Java.

There are many ways to split a string in Java, but one of the most common methods is by using the `String.split()` method. This method accepts a regular expression as a parameter and splits the given string at every match.

Let's consider an example where we want to split a string each time we encounter the substring `'laugh'`. We can do this by creating a Java String object with the value `'WelcomeLaughtoLaughtutorialsPoint'` and using the `split()` method to divide it into substrings.

Here is an example program that demonstrates how to use the `String.split()` method:

```

String s = 'WelcomeLaughtoLaughtutorialsPoint';

String'' tokensVal = s.split('laugh');

```

In this example, the `split()` method splits the string `'s'` into an array of substrings each time it encounters the substring `'laugh'`. The resulting array is stored in the `tokensVal` variable.

We can also use the `split()` method to split a string and count the tokens without providing any limit to the string. For example:

```

String str = 'Hello, how are you';

String'' tokens = str.split(',');

int tokensVal = tokens.length;

System.out.println('Count of tokens = ' + tokensVal);

```

In this example, the `split()` method splits the string `'str'` into an array of substrings each time it encounters a comma. The resulting array is stored in the `tokens` variable and its length is used to count the number of tokens.

The `String.split()` method has two polymorphic variants: one that accepts a regular expression as a parameter and another that accepts a regular expression and a limit.

Here is an example program that demonstrates how to use the `split()` method with a limit:

```

String str = 'Hello, how are you';

String'' tokensVal = str.split(',', 3);

System.out.println('Count of tokens = ' + tokensVal.length);

```

In this example, the `split()` method splits the string `'str'` into an array of substrings each time it encounters a comma. The resulting array is stored in the `tokensVal` variable and its length is used to count the number of tokens.

In conclusion, the `String.split()` method is a powerful tool that can be used to split strings into arrays of substrings in Java. By using regular expressions and limits, developers can customize how they want their strings to be divided.
