There are no global variables in java, but there are global classes with public fields I want use the trailimage variable (declared in the makeobj function) in other functions. You can use static import feature of java 5 to make it look almost like global variables.

I am new to java programming 690 is it possible to define a global variable in a javascript function Can anyone tell what is the difference between global and local variable in java?

We may want to avoid that because 1) the string is too big.

Oop has no global variables because it is not a language Even java (for example) has no global variables in the c / fortran sense Statics have to be qualified by the name of the enclosing class at some point A c or fortran global is truly global, and that's one of the things that makes them dangerous.

0 you can create a public static variable instead of global variable that would be a better idea One other approach is to create a class that follows the singleton pattern, so there can only be one instance of the class and keep the variable in the singleton class and access it with get and set methods The only type of variable you can possibly declare as global is public static final variables of a class, which can be accessed anywhere The variable you are defining above are instance variables or member variables.

If you want to make some variable global then you would need to declare the variable outside the method

In java, you cannot declare static variables inside method (even if it is static) because inside method all variables are local variables that has no existence outside this method thats why they can't be static. I want to set up some global variables that are accessible by multiple classes Examples of these global variables would be things like a boolean flag testmodeon, a language setting, current local server, time display format, etc.
