java array copy

// Shallow copy
int[] src = {1,2,3,4,5};
int[] dst = Arrays.copyOf(src, src.length);

// Deep copy
int[] dst2 = new int[src.length];
for(int i = 0; i < src.length; i++){
	dst2[i] = src[i];
}

java copy array

int[] a = {1,2,3,4,5};
int[] b = Arrays.copyOf(a, a.length);

copy array in java

int[] src  = new int[]{1,2,3,4,5};
int[] dest = new int[5];

System.arraycopy( src, 0, dest, 0, src.length );

how to make a copy of an array java

int a[] = {1, 8, 3}; 
  
// Copy elements of a[] to b[] 
int b[] = a.clone();

copy elements of array in java

public static void arraycopy(Object source_arr, int sourcePos,
                             Object dest_arr, int destPos,
                             int len)
/* Parameters : 
source_arr : array to be copied from
sourcePos : starting position in source array from where to copy
dest_arr : array to be copied in
destPos : starting position in destination array, where to copy in
len : total no. of components to be copied
*/

how to copy array in java

// method 
public static int [] copyArray(int [] arr){
      int [] copyArr = new int[arr.length];
      for (int i = 0; i < copyArr.length; i++){
            copyArr[i] = arr[i];
       }
      return copyArr;
}

// Arrays. method 
int[] copyCat = Arrays.copyOf(arr, arr.length);

// System 
System.arraycopy(x,0,y,0,5); // 5 is array's length 

// clone 
y = x.clone(); 

array copy java

// java.util.Arrays.copyOf() method is in java.util.Arrays class.
// It copies the specified array, truncating or padding with false
// (if necessary) so the copy has the specified length.
int[] src = {1,2,3,4};
int[] dst = Arrays.copyOf(src, src.length);

// clone() method.
int[] arrClone = src.clone()

Java Copying Arrays Using arraycopy() method

arraycopy(Object src, int srcPos,Object dest, int destPos, int length)
