How to use the BASE64 framework in the Java library for data encoding and decoding

In the Java class library, we can use the Base64 framework for data encoding and decoding operations.Base64 encoding is a encoding method that converts binary data into printable characters. It is often used in scenarios that require text formats that require text formats, including pictures, audio, video, etc. First of all, we need to import the Base64 library of Java: import java.util.Base64; Next, we can use the static method of Base64 to cod and decoding. 1. Code the data: String OriginalData = "Hello, Hello!";; String encodedData = Base64.getEncoder().encodeToString(originalData.getBytes()); System.out.println("Encoded data: " + encodedData); The above code encodes the original data "Hello, Hello!"The encoded data is: "SGVSBG8SIOS9OWLVQ ==". 2. Decoding the data: String encodedData = "SGVsbG8sIOS9oOWlvQ=="; byte[] decodedBytes = Base64.getDecoder().decode(encodedData); String decodedData = new String(decodedBytes); System.out.println("Decoded data: " + decodedData); The above code will decode the coded data "SGVSBG8SIOS9OWLVQ ==" and print out the decoded results.The decoding data is: "Hello, hello!". It should be noted that the above code uses the Base64 library of Java 8 and above.If you use it below the Java 8 version, you can use a third -party library, such as the Base64 of Apache Commons Codec. In summary, through the Base64 framework in the Java class library, we can easily perform data encoding and decoding operations to meet the needs of network transmission and storage data.
