The isCharsetDetected() method is a built-in method of the java.nio.charset.CharsetDecoder class which tells whether or not this decoder has yet detected a charset. The default implementation of this method always throws an UnsupportedOperationException. It should be overridden by auto-detecting decoders to return true once the input charset has been determined.
public boolean isCharsetDetected()
Parameters: The function does not accepts any parameter.
Return Value: The function returns a boolean value stating if this CharsetDecoder has yet detected a charset.
Exception: It throws UnsupportedOperationException if this decoder does not implement an auto-detecting charset
Below is the implementation of the above function:
CharsetDecoder: sun.nio.cs.ISO_8859_1$Decoder@232204a1 java.lang.UnsupportedOperationException
CharsetDecoder: sun.nio.cs.ext.DoubleByte$Decoder@232204a1 java.lang.UnsupportedOperationException
