The type "bool" is a fundamental C++ type that can take on the values "true" and "false". When a non-bool x is converted to a bool, non-zero becomes true and zero becomes false, as if you had written x != 0. When bool is converted to non-bool, true becomes 1 and false ...
Integer is a class, no diffeeent from any other in the java language. Variables of type Integer store the references to Integer Objects. Note that every primiry type has wrapper class: byte has Byte long has Long boolean has Boolean float has Float double has Double Wrapper class inherit fr...

There is no unsigned integer type in Java. Type checking and type requirements are much tighter in Java than in C++. Unlike C++, Java provides a truebooleantype.Conditional expressions in Java must evaluate tobooleanrather than to integer, as is the case in C++. Statements such asif(x+y)....
