To exit a while loop  use Break  This will not allow to loop to process any conditions that are placed inside  make sure to have this inside the loop  as you cannot place it outside the loop

You can do multiple condition logical tests within the while   check using the same rules as within any logical check   while   obj    null              do stuff       works  as does  while   value  gt  5  amp  amp  value  lt  10              do stuff         are valid  The conditionals are checked on each iteration through the loop  As soon as one doesn t match  the while   loop is exited  You can also use break   while   value  gt  5           if   value  gt  10     break

break is what you re looking for   while  true        if  obj    null  break      alternatively  restructure your loop   while  obj    null           do stuff     or   do          do stuff   while  obj    null

if you write while true   its means that loop will not stop in any situation for stop this loop you have to use break statement between while block   package com java demo           author Ankit Sood Apr 20  2017     public class Demo                   The main method                 param args                   the arguments             public static void main String   args               Initialize while loop            while  true                                 You have to declare some condition to stop while loop                 In which situation or condition you want to terminate while loop                conditions like  if condition  break   if var  10  break  etc                                    break keyword is for stop while loop                 break

Finding a while   do construct with while true  in my code would make my eyes bleed  Use a standard while loop instead    while  obj    null               And take a look at the link Yacoby provided in his answer  and this one too  Seriously    The while and do-while Statements

You can use  break   already mentioned in the answers above  If you need to return some values  You can use  return  like the code below                                                            while true          if some condition               do something              return           else              do something              return                   in this case  this while is in under a method which is returning some kind of values

Use break   while  true                 if  obj    null            break                       However  if your code looks exactly like you have specified you can use a normal while loop and change the condition to obj    null   while  obj    null

Take a look at the Java    Tutorials by Oracle   But basically  as dacwe said  use break   If you can it is often clearer to avoid using break and put the check as a condition of the while loop  or using something like a do while loop  This isn t always possible though
