- For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither. Don't forget to identify the last statement at the very bottom, Member m = new BoardMember();, as legal or illegal and widening or narrowing conversion.Consider te following declaration:enum fruitType (ORANGE, APPLE, BANANA, GRAPE, STRAWBERRY, MANGO GUAVA, PINEAPPLE, KIWI); fruitType fruit;a. What is the value of static_cast <int>(STRAWBERRY)?b. What is the value, if any, of the expresion?static_cast<fruitType>(static_cast<int>(MANGO) - 2) c. What is the value if any, of the expression?static_cast<fruitType>(static_cast<int>(GRAPE) + 2)d, What if the value, if any, of the expression: BANANA <= KIWIe. What is the output, if any, of the following code?for(fruit = BANANA,; fruit < PINEAPPLE; fruit++) cout << static_cast<int>(fruit) << ", "; cout << endl;. Read the following program and answer the questions given at the end. class Example { int y, z; static int x; static{x=5;} Example () { x=x+1; y=0; z=0; } Example (int a, int y, int z) { x=a; y=y; z=z; } void show(){ S.O.P(x + y+ z);}} How many data members are included in class Example, identify. What is the purpose of static block in the code. The program involves the problem of instance variable hiding. How the problem can be resolved. what will be the output of the program for the following object Example ob1=new Example (4,5,3) and Example ob2=new Example () ;
- Decidewhich of the following statements is either true or false and re-correct the false ones.1. The value of the following logical expression is true (1 + 2 == 2) || (4 - 4 == 0)2. In Java, once a variable is declared, it will be visible and could be used anywhere in theprogram.3. Strings are primitive data type in Java.4. In Java, we can initialize a variable during its declaration.5. do ... while repetition statement gives full control on the code block to be repeated.6. All binary operators except for the assignment operators are evaluated from Left to Right7. A ragged 2D array is a 2D array in which each column may contain different number of rows.8. Each row in a 2D array could be dealt with as 1D array.9. The following statement creates and initializes the array x:int x[] = {10, 20, 30, 40, 50};10. A Java program may contain more than one method with the same signaturejava, Describe the difference(s) between the following two sets of code, neither of which reaches a terminating condition. public void forever() { while (true); } public void foreverMore() { foreverMore(); }Read the following JAVA program and answer the questions given at the end. class Example { int y, z; static int x; static{x=5;} Example () { x=x+1; y=0; z=0; } Example (int a, int y, int z) { x=a; y=y; z=z; } void show(){ S.O.P(x + y+ z);}} How many data members are included in class Example, identify. What is the purpose of static block in the code. The program involves the problem of instance variable hiding. How the problem can be resolved. what will be the output of the program for the following object Example ob1=new Example (4,5,3) and Example ob2=new Example () ; without resolving the problem of instance variable hiding and after resolving the problem.
