Is true or false in Java?

In the boolean type, there are only two possible values: true and false. … A boolean variable is only capable of storing either the value true or the value false. The words true and false are built-in literals in Java that can be used right in the code.

Does the integer 0 == false?

0 and 1 are type ‘number’ but in a Boolean expression, 0 casts to false and 1 casts to true . Since a Boolean expression can only ever yield a Boolean, any expression that is not expressly true or false is evaluated in terms of truthy and falsy. Zero is the only number that evaluates to falsy.

Does zero return false?

In JavaScript “0” is equal to false because “0” is of type string but when it tested for equality the automatic type conversion of JavaScript comes into effect and converts the “0” to its numeric value which is 0 and as we know 0 represents false value. So, “0” equals to false.
