In Java, the assert keyword is followed by a Boolean true or false statement or an expression that returns a Boolean statement at runtime.
Assertion statements can allow a programmer to test assumptions about their programs. For example, in the case of a program calculating the speed of particles, it can be generally assumed that its speed is slower than the speed of light. If an assert is made in code expressing “this is true,” an error will be returned in the event that the assert proves not to be true.
When Java assert shows to be true, it can help confirm code and increase confidence. This capacity makes Java assert a quick and effective method of debugging code. Assertions can also make code more manageable for the future by documenting the code’s functionality.
