We can simplify this function by using the ternary operator: publicintbooleanPrimitiveToIntTernary(booleanfoo){return(foo) ?1:0; } This approach uses primitive data types (booleanandint)to make the conversion. As a result, we obtain 1 when the boolean expression istrue.Otherwise, the method ...
The most straightforward way to toggle a primitivebooleanvariable would be usingthe NOT operator(!). Let’s create a test to see how it works: boolean b = true; b = !b; assertFalse(b); b = !b; assertTrue(b); If we run this test, it passes. Therefore, every time we perform th...
