 public class AssertionError extends Error Thrown to indicate that an assertion has failed.The seven one-argument public constructors provided by this class ensure that the assertion error returned by the invocation: new AssertionError(expression)has as its detail message the string conversion of expression (as defined in section 15.18.1.1 of The Java™ Language Specification), regardless of the type of expression.- Since:

Constructor Detail- 
AssertionErrorpublic AssertionError() Constructs an AssertionError with no detail message.
 - 
AssertionErrorpublic AssertionError(Object detailMessage) Constructs an AssertionError with its detail message derived from the specified object, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.If the specified object is an instance of Throwable, it becomes the cause of the newly constructed assertion error.- Parameters:
- detailMessage- value to be used in constructing detail message
- See Also:
- Throwable.getCause()
 
 - 
AssertionErrorpublic AssertionError(boolean detailMessage) Constructs an AssertionError with its detail message derived from the specifiedboolean, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(char detailMessage) Constructs an AssertionError with its detail message derived from the specifiedchar, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(int detailMessage) Constructs an AssertionError with its detail message derived from the specifiedint, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(long detailMessage) Constructs an AssertionError with its detail message derived from the specifiedlong, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(float detailMessage) Constructs an AssertionError with its detail message derived from the specifiedfloat, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(double detailMessage) Constructs an AssertionError with its detail message derived from the specifieddouble, which is converted to a string as defined in section 15.18.1.1 of The Java™ Language Specification.- Parameters:
- detailMessage- value to be used in constructing detail message
 
 - 
AssertionErrorpublic AssertionError(String message, Throwable cause) Constructs a newAssertionErrorwith the specified detail message and cause.Note that the detail message associated with causeis not automatically incorporated in this error's detail message.- Parameters:
- message- the detail message, may be- null
- cause- the cause, may be- null
