I heard several times that in using boolean equals(Object o) to compare Strings, it\'s better to put the constant on the left side of the function as in the following:
I\'m looking to replace the开发者_运维百科 text inside a <nobr> but I can\'t figure out how.
I stumbled across the source of AtomicInteger and realized that new AtomicInteger(0).equals(new AtomicInteger(0))
I have this class: private static class ClassA{ int id; String name; public ClassA(int id, String name){ this.id开发者_Python百科= id;

I can\'t find any documentation on "not equal" sign in Visual Prolog. Please provide the right solution of this problem:
Maybe I\'ve been working too long on Java without really understanding some of its basics. I do understand that == is for object reference equality and .equals() is for object value equality.
Say y开发者_如何转开发ou have three strings, String s1 = \"string one\"; String s2 = new String(\"string one\");
Consider the following test case, is it a bad practice to use the hashCode method inside of equals as a convenient shortcut?
I need to implement equals() and hashCode() for an A开发者_开发百科ddress class. I believe,the non null fields are taken to determine hashCode() and equals().In my application,Any of the fields excep
