object or reference variable

When the code stone in the memery, the "abc" is seted on the stack, "new String()" will create the object but not create a char[] as "abc":

public String(String original) {

int size = original.count;

char[] originalValue = original.value;

char[] v;

if (originalValue.length > size) {

// The array representing the String is bigger than the new

// String itself. Perhaps this constructor is being called

// in order to trim the baggage, so make a copy of the array.

v = new char[size];

System.arraycopy(originalValue, original.offset, v, 0, size);

} else {

// The array representing the String is the same

// size as the String, so no point in making a copy.

v = originalValue;

}

this.offset = 0;

this.count = size;

this.value = v;

}
