check Equal and Not Equal conditons for double values
Solution 1
If you're using a double
(the primitive type) then a
and b
must not be equal.
double a = 1.0;
double b = 1.0;
System.out.println(a == b);
If .equals()
works you're probably using the object wrapper type Double
. Also, the equivalent of !=
with .equals()
is
!a.equals(b)
Edit
Also,
else if ((a!=b||c!=d||e!=f))
{
//My code here in case false condition
}
(Unless I'm missing something) should just be
else
{
//My code here in case false condition
}
if you really want invert your test conditions and test again,
else if (!(a==b||c==d||e==f))
Or use De Morgan's Laws
else if (a != b && c != d && e != f)
Solution 2
You can use
!a.equals(b) || !c.equals(d) || !e.equals(f)
Well with double data type you can use
==,!= (you should try to use these first.. )

I am facing difficulty in comparing two
double values
using==
and!=
.I have created 6 double variables and trying to compare in
If
condition.double a,b,c,d,e,f; if((a==b||c==d||e==f)) { //My code here in case of true condition } else if ((a!=b||c!=d||e!=f)) { //My code here in case false condition }
Though my condition is
a and b are equal
control is going toelse if
partSo I have tried
a.equals(b)
for equal condition, Which is working fine for me.My query here is how can I check
a not equal b
. I have searched the web but I found only to use!=
but somehow this is not working for me.
