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