I\'m having a real tough time on this problem. Can someone please provide this code in Java??
Create a class, ObjCompare, with a simple generic method, compareObj that
compares any two objects whose class implements Comparable. The
compareObj method must use the equals() method of the Comparable
objects, and returns true is they are equal, otherwise it returns false. Test
your class by comparing two Integers, two Doubles, two Strings, and two
Characters. What happens when you attempt to compare diverse types? For
instance try comparing an Integer to a Double; and, try comparing an Integer
to a String. Partial sample output:
1 is NOT equal to 0
1 is equal to 1
1.0 is NOT equal to -2.2
1.0 is equal to 1.0
Welcome is NOT equal to Home
Welcome is equal to Welcome
& is NOT equal to #
& is equal to &
Solution
Hi, Please find my implementation.
Please let me know in case of any issue.
########### ObjCompare.java ############
public class ObjCompare {
// takes two parameters that implements Comparable
public <T extends Comparable<T>> boolean compareObj(T obj1, T obj2){
// calling object \'equals\' method
if(obj1.equals(obj2))
return true;
else
return false;
}
}
############ ObjCompareTest.java ###########
public class ObjCompareTest {
public static void main(String[] args) {
// creating an Object of ObjCompare
ObjCompare compare = new ObjCompare();
Integer i1 = new Integer(34);
Integer i2 = new Integer(33);
Integer i3 = new Integer(34);
if(compare.compareObj(i1, i2)){
System.out.println(i1 +\" is equal to \"+i2);
}else{
System.out.println(i1 +\"is NOT to \"+i2);
}
if(compare.compareObj(i1, i3)){
System.out.println(i1 +\" is equal to \"+i3);
}else{
System.out.println(i1 +\"is NOT to \"+i3);
}
String s1 = \"Welcome\";
String s2 = new String(\"Welcome\");
if(compare.compareObj(s1, s2)){
System.out.println(s1 +\" is equal to \"+s2);
}else{
System.out.println(s1 +\"is NOT to \"+s2);
}
}
}
/*
Sample Run:
34is NOT to 33
34 is equal to 34
Welcome is equal to Welcome
*/
IF you call compareObj method with two different type of object, it throws compile time error
