The LocalTime instance can be obtained from a string value using the parse() method in the LocalTime class in Java. This method requires a single parameter i.e. the string which is to be parsed. This string cannot be null. Also, it returns the LocalTime instance obtained from the string value that was passed as a parameter.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalTime lt = LocalTime.parse("23:15:30"); System.out.println("The LocalTime is: " + lt); } }OutputThe LocalTime is: 23:15:30Now ...

You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You cannot overload function declarations that differ only by return type.The function overloading is basically the compile time polymorphism. It checks the function signature. If the signatures are not same, then they can be overloaded. The return type of a function does not create any effect on function overloading. Same function signature with different return type will not be overloaded.Following is the example where ... Read More
