How can Boolean be used in Java?
An expression is anything that can be evaluated ("calculated"), to get a value. Numeric expressions are more common: anything that you can calculate, and get a number. For example, if a and b are numbers, a + b will give you another number - it is therefore a numeric expression. The variables by themselves are also numeric expressions.A boolean expression is anything that you can evaluate and get a result that is boolean, i.e., either true or false. Here are some examples:a == ba > ba >= 5 && a ba >= 5 && a ba >= 5 && a ba >= 5 && a
You use the operator to reverse the meaning of a Boolean expression?
The NOT operator. E.g., NOT TRUE evaluates to FALSE while NOT FALSE evaluates to TRUE.
Define an expression that evaluates to true when i equals j?
In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.
Which method is default by true in java?
I don't understand what you mean with "default by true"? Please clarify your question. A Java method can have zero or more parameters, and it must have one return value. Any of these can be declared as "boolean", in which case the value can be either true or false.
Are true false and null Java keywords?
True and false are literals(special built-in value) in java and cannot be used as keywords.
