I'm trying to compare 4 values in a program.

Long val1 = 127l;
Long val2 = 127l;
Long val3 = 128l;
Long val4 = 128l;
Log.e("XXXX",(val1==val2)+" "+(val3==val4));

This gives me val1l == val2l is true and val3' == val4l is false. What is the reason behind this output. I think it's coming because of the wrapper class. Please help me to clear this.

On a point of style: use `127L` rather than `127l`, because the latter looks a lot like `1271`. – Andy Turner Jul 03 '17 at 07:02
