But there is a length field available in the array that can be used to find the length or size of the array. String string = "asdf"; byte [] stringBytes = string.getBytes (); ByteArrayOutputStream outputStream = outputStream = new ByteArrayOutputStream (); outputStream.write (new byte [100 - stringBytes.length]); outputStream.write (stringBytes); byte [] result = outputStream.toByteArray (); java. boolean [] array = new boolean [size]; Or use java.util.Arrays to fill the entire array with Boolean.FALSE. After the declaration of an empty array, we can initialize it using different ways. Features of Dynamic Array. If componentType represents an array class, the number of dimensions of the new array is equal to t You can declare the array with the syntax below: dataType [ ] nameOfArray; dataType: the type of data you want to put in the array. We can also say that the size or length of the array is 10. The index number greater than the size of the array may yield invalid data.
