A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.

No.A char is a single Unicode character. It is stored as a primitive (i.e., non-object) data. A string can be considered as an array of chars - Java stores it as an object.No.A char is a single Unicode character. It is stored as a primitive (i.e., non-object) data.

Objects are stored in an area of memory called the "heap", whilst reference variables are stored in the "stack". These are both parts of the computer's RAM memory; the Java Virtual Machine (JVM) simply reserves part of the memory available to it for the stack and for the heap, and manages them accordingly.
An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap. The heap is the part of memory which is used to store objects.An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap.

You can specify the starting and maximum heap sizes when you launch a Java program by using the command line switches: -Xms<size> set initial Java heap size -Xmx<size> set maximum Java heap size Example: The following line will run the MyProgram Java program with 64-128mb heap space. java -Xms64m -Xmx128m MyProgram
