The Java String getBytes function is used to convert a string into a sequence of bytes. This function takes an optional parameter that specifies the character encoding to use for the conversion. If no encoding is specified, the default encoding of the platform is used. The resulting byte array can be used for various purposes, such as writing the string to a file or sending it over a network. It is important to note that the size of the resulting byte array may be larger than the length of the original string, as some characters may require multiple bytes to represent in certain encodings.

Java String getBytes in Javascript With Example Code
Java String getBytes method is used to convert a string into a sequence of bytes. This method is useful when we need to send data over a network or store it in a file. In JavaScript, we can use the TextEncoder API to achieve the same functionality.
The TextEncoder API is a built-in JavaScript API that provides a way to encode a string into a sequence of bytes using a specific encoding. The encoding can be specified as a parameter to the TextEncoder constructor. The default encoding is UTF-8.
Here is an example code snippet that demonstrates how to use the TextEncoder API to encode a string into a sequence of bytes:
const encoder = new TextEncoder();
const str = "Hello, World!";
const bytes = encoder.encode(str);
console.log(bytes);
In this example, we create a new TextEncoder object and use it to encode the string “Hello, World!” into a sequence of bytes. The resulting bytes are stored in the bytes variable, which we then log to the console.
Using the TextEncoder API is a simple and efficient way to convert a string into a sequence of bytes in JavaScript.
Equivalent of Java String getBytes in Javascript
In conclusion, the equivalent function of Java’s String getBytes() in JavaScript is the TextEncoder.encode() method. This method allows developers to encode a string into a specified format, such as UTF-8 or UTF-16, and returns a Uint8Array containing the encoded data. This function is useful for sending data over the network or storing it in a database. It is important to note that the TextEncoder.encode() method is not supported in all browsers, so developers should check for compatibility before using it in their code. Overall, the TextEncoder.encode() method is a powerful tool for encoding strings in JavaScript and can be a valuable addition to any developer’s toolkit.
