java - Less than two variables -

i have tried search as can it's kinda hard when beginner. anyway im trying learn java , im stuck on question says "var1 can bigger var2 or var3 not both. , im supposed answer boolean value.

e = var1 > var2 || var1 > var3 && var1 < var2 + var3; 

if end doing total sum of var2 , var3. how do like

var1 < var2 , var3; 

you can use exclusive-or operator:

(var1 > var2) ^ (var1 > var3) 

a ^ b true if , if either a or b (but not both) true:

  b  a^b --------- 0  0   0 0  1   1 1  0   1 1  1   0
