copyOf
public static <T> T[] copyOf(T[] original,
int newLength)
- Copies the specified array, truncating or padding with nulls (if necessary)
so the copy has the specified length. For all indices that are
valid in both the original array and the copy, the two arrays will
contain identical values. For any indices that are valid in the
copy but not the original, the copy will contain null.
Such indices will exist if and only if the specified length
is greater than that of the original array.
The resulting array is of exactly the same class as the original array.
- Parameters:
original
- the array to be copiednewLength
- the length of the copy to be returned
- Returns:
- a copy of the original array, truncated or padded with nulls
to obtain the specified length
- Throws:
java.lang.NegativeArraySizeException
- if newLength is negative
java.lang.NullPointerException
- if original is null- Since:
- 1.6
copyOf
public static <T,U> T[] copyOf(U[] original,
int newLength,
java.lang.Class<? extends T[]> newType)
- Copies the specified array, truncating or padding with nulls (if necessary)
so the copy has the specified length. For all indices that are
valid in both the original array and the copy, the two arrays will
contain identical values. For any indices that are valid in the
copy but not the original, the copy will contain null.
Such indices will exist if and only if the specified length
is greater than that of the original array.
The resulting array is of the class newType.
- Parameters:
original
- the array to be copiednewLength
- the length of the copy to be returnednewType
- the class of the copy to be returned
- Returns:
- a copy of the original array, truncated or padded with nulls
to obtain the specified length
- Throws:
java.lang.NegativeArraySizeException
- if newLength is negative
java.lang.NullPointerException
- if original is null
java.lang.ArrayStoreException
- if an element copied from
original is not of a runtime type that can be stored in
an array of class newType- Since:
- 1.6
