Converting objects to primitive data types and vice versa: When one reference object can be typecast into other reference object. It is called as casting object. Objects and primitive datatypes are very different in Java. Converting objects to primitive data types and primitive datatypes to objects are not possible in any circumstance. The programmer can use “java.lang” package for converting primitive data types to objects and vice versa. Here most of the classes have same names as the datatypes and expect that the class names start with a capital letter like “Float” instead of “float”, “Short” instead of “short”. The two classes have different names corresponding to the datatypes: “Integer” instead of “int” and “Character” instead of “char”.

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }
