Step by step
Solved in 2 steps
- public float method1(int z) { return (float) z; } // in another class we created an object of the first class and within in it: int y = tester.method1(); are there any errors ? with explanation pleaseTrue or False _6. A method can return one value ___7. A method can call itself. ___ 8. A method can take more than one parameter. 9. A method can call another method which can call a third method. 10. To calculate the value of 2.53.5, you use the Java statement Math.pow(3.5, 2.5);When calling a method in Java, arguments are sent by value rather than by reference. Can you elaborate on what this entails?
- 7) In Java, call-by-value is only used with: objects primitive types this all of the above Answer: 8) The parameter this refers to instance variables local variables global variables the calling object Answer: Pls answer these mcq's 9) When the parameters in a method have the same as instance variables you can differentiate them by using the _____ parameter. String hidden default this Answer:When a method is __________, it means that multiple methods in the same class have the same name but use different types of parameters. a. emulated b. versioned c. threaded d. overloadedANSWER IN JAVA Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.
