Writing file using bytearrayoutputstream

Here, we have created an output stream that will write data to an array of bytes with default size 32 bytes. However, we can change the default size of the array. The ByteArrayOutputStream class provides the implementation of the different methods present in the OutputStream class. Note : The getBytes method used in the program converts a string into an array of bytes.

In the above example, we have created an array of bytes to store the data returned by the toByteArray method. We then have used the for loop to access each byte from the array. Here, each byte is converted into the corresponding character using typecasting. However, the close method has no effect in ByteArrayOutputStream class.

We can use the methods of this class even after the close method is called. Course Index Explore Programiz. Java for Loop. Arrays in Java. Interfaces in Java. Java ArrayList. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.

This stream holds a data copy and forwards the data into several streams. Based on the size of the data, the stream gets automatically larger.

This class gets inherited from the package Java. Moreover, each character of the byte array gets converted to an upper case and printed. In this program, two files byte1 and byte2, are created for copying the content from byte1 to byte2. Java program to implement bytearrayoutputstream using the methods toByteArray and write buff, offset, maximum length.
