EncodeTools Tutorial

The EncodeTools class provides methods for URL encoding, URL decoding, Base64 encoding, and Base64 decoding. These methods can be used to handle string encoding and decoding for various purposes, such as preparing strings for HTTP requests or encoding binary data.

Methods

1. urlEncode(String str)

Encodes a string using URL encoding.

• Parameters:
  • str: The input string to encode.
• Returns: The URL-encoded string.

Example:

String encoded = EncodeTools.urlEncode("Hello World!");
// encoded will be "Hello%20World%21"

2. urlDecode(String str)

Decodes a URL-encoded string.

• Parameters:
  • str: The URL-encoded string to decode.
• Returns: The decoded string.

Example:

String decoded = EncodeTools.urlDecode("Hello%20World%21");
// decoded will be "Hello World!"

3. base64Encode(byte[] bytes)

Encodes a byte array using Base64 encoding.

• Parameters:
  • bytes: The byte array to encode.
• Returns: The Base64-encoded byte array.

Example:

byte[] encodedBytes = EncodeTools.base64Encode("Hello World!".getBytes());
// encodedBytes will be the Base64-encoded byte array

4. base64EncodeToString(byte[] bytes)

Encodes a byte array using Base64 encoding and returns the result as a string.

• Parameters:
  • bytes: The byte array to encode.
• Returns: The Base64-encoded string.

Example:

String encodedString = EncodeTools.base64EncodeToString("Hello World!".getBytes());
// encodedString will be "SGVsbG8gV29ybGQh"

5. base64Decode(String str)

Decodes a Base64-encoded string.

• Parameters:
  • str: The Base64-encoded string to decode.
• Returns: The decoded byte array.

Example:

byte[] decodedBytes = EncodeTools.base64Decode("SGVsbG8gV29ybGQh");
// decodedBytes will be the decoded byte array

6. base64DecodeToString(String str)

Decodes a Base64-encoded string and returns the result as a string.

• Parameters:
  • str: The Base64-encoded string to decode.
• Returns: The decoded string.

Example:

String decodedString = EncodeTools.base64DecodeToString("SGVsbG8gV29ybGQh");
// decodedString will be "Hello World!"
