DoubleBuffer arrayOffset() method in Java
The offset of the first element of the buffer inside the buffer array is obtained using the method arrayOffset() in the class java.nio.DoubleBuffer. If the buffer backed by the array is read-only, then the ReadOnlyBufferException is thrown.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { DoubleBuffer buffer = DoubleBuffer.allocate(5); buffer.put(4.5D); buffer.put(1.2D); buffer.put(3.9D); ...
Read MoreFix for java.math.BigInteger cannot be cast to java.lang.Integer?
You can typecast with the help of method intValue(). The syntax is as follows −Integer yourVariableName=((BigInteger) yourBigIntegerValue).intValue();Here is the Java code to convert java.math.BigInteger cast to java.lang.Integer. The code is as follows −Example Live Demoimport java.math.BigInteger; public class BigIntegerToInteger { public static void main(String []args) { BigInteger bigValue [] = new BigInteger[5]; bigValue[0] = new BigInteger("6464764"); bigValue[1] = new BigInteger("212112221122"); bigValue[2] = new BigInteger("76475"); bigValue[3] = new BigInteger("94874747"); bigValue[4] = new BigInteger("2635474"); for(int i = 0; i< bigValue.length; i++) ...
Read MoreShortBuffer order() Method in Java
The byte order of the buffer can be obtained using the method order() in the class java.nio.ShortBuffer. This method requires no parameters and it returns the byte order of the buffer.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ShortBuffer buffer = ShortBuffer.allocate(n); buffer.put((short)12); buffer.put((short)91); buffer.put((short)25); buffer.put((short)18); buffer.put((short)30); ...
Read MoreByteBuffer asShortBuffer() method in Java
A view of the ByteBuffer can be created as a ShortBuffer using the asShortBuffer() method in the class java.nio.ByteBuffer. This method requires no parameters and it returns a short buffer as required. This buffer reflects the changes made to the original buffer and vice versa.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 50; try { ByteBuffer bufferB = ByteBuffer.allocate(n); ShortBuffer bufferS = bufferB.asShortBuffer(); ...
Read MoreByteBuffer compact() method in Java
The buffer can be compacted using the compact() method in the class java.nio.ByteBuffer. This method does not require a parameter and it returns the new compacted ByteBuffer with the same content as the original buffer. If the buffer is read-only, then the ReadOnlyBufferException is thrown.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ByteBuffer buffer ...
Read MoreByteBuffer duplicate() method in Java
A duplicate buffer of a buffer can be created using the method duplicate() in the class java.nio.ByteBuffer. This duplicate buffer is identical to the original buffer. The method duplicate() returns the duplicate buffer that was created.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ByteBuffer buffer1 = ByteBuffer.allocate(5); buffer1.put((byte)1); buffer1.put((byte)2); buffer1.put((byte)3); buffer1.put((byte)4); ...
Read MoreByteBuffer get() method in Java
The value at the current position of the buffer is read and then incremented using the method get() in the class java.nio.ByteBuffer. This method returns the value that is at the current buffer position. Also, the BufferUnderflowException is thrown if underflow situation occurs.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ByteBuffer buffer = ByteBuffer.allocate(n); ...
Read MoreByteBuffer asLongBuffer() method in Java
A view of the ByteBuffer can be created as a LongBuffer using the asLongBuffer() method in the class java.nio.ByteBuffer. This method requires no parameters and it returns a long buffer as required. This buffer reflects the changes made to the original buffer and vice versa.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 50; try { ByteBuffer bufferB = ByteBuffer.allocate(n); LongBuffer bufferL = bufferB.asLongBuffer(); ...
Read MoreByteBuffer asReadOnlyBuffer() method in Java
A read-only byte buffer can be created using the contents of a buffer with the method asReadOnlyBuffer() in the class java.nio.ByteBuffer. The new buffer cannot have any modifications as it is a read-only buffer. However, the capacity, positions, limits etc. of the new buffer are the same as the previous buffer.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ByteBuffer buffer = ByteBuffer.allocate(5); ...
Read MoreByteBuffer asDoubleBuffer() method in Java
A view of the ByteBuffer can be created as a DoubleBuffer using the asDoubleBuffer() method in the class java.nio.ByteBuffer. This method requires no parameters and it returns a double buffer as required. This buffer reflects the changes made to the original buffer and vice versa.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 50; try { ByteBuffer bufferB = ByteBuffer.allocate(n); DoubleBuffer bufferD = bufferB.asDoubleBuffer(); ...
