浅拷贝是一种只将字段的值从一个对象复制到另一个对象。A shallow copy is one in whichwe only copy values of fieldsfrom one object to another: @TestpublicvoidwhenShallowCopying_thenObjectsShouldNotBeSame(){Addressaddress=newAddress("Downing St 10","London","England");Userpm=newUser("Prime","M...

In this example,Arrays.copyOf()is used to create an exact copy oforiginalArray. The new arraycopiedArraycontains all elements from the original array. Example 2: Copying with a Larger Size importjava.util.Arrays;publicclassCopyOfLargerExample{publicstaticvoidmain(String[]args){int[]originalArray...
System.arraycopy() is a method in Java that can be used to copy elements from one array to another. It can be used to remove an element from an array by copying all elements before the element to be removed, and then copying all elements after the element to be removed, starting from...
If the src and dest arguments refer to the same array object, then the copying is performed as if the components at positions srcPos through srcPos+length-1 were first copied to a temporary array with length components and then the contents of the temporary array were copied into positions des...
After copying the items from the old array, the new array is truncated or padded with nulls to obtain the required length. intarray[]={0,1,2,3,4,5};int[]smallCopy=Arrays.copyOf(array,3);//[0, 1, 2]int[]largeCopy=Arrays.copyOf(array,10);//[0, 1, 2, 3, 4, 5, 0, 0...
