arraycopy() with String[][]

[Juhan Voolaid]

Hi

I don't know how to use System.arraycopy() method with 2 dim. arrays.

Lets say i have an existing array:
String existing [10][2] and new array
String newArray[][]= new String[10][2];

now how to use arraycopy() that "newArray" is a copy of "existing"?

Hi,

  
 
//ArrayCopy.java
 
class ArrayCopy {
 
public static void main(String[] args) {

char[][] arrSrc = new char[][]{
{'A', 'B', 'C'},
{'E', 'F', 'G'}};
char[][] arrDest = new char[2][3];

System.arraycopy(arrSrc[0], 0, arrDest[0], 0, 3);
System.arraycopy(arrSrc[1], 0, arrDest[1], 0, 3);
 
for (int i=0; i<2 ;i++ ) {

for (int j=0;j<3 ;j++ ) {
System.out.println(arrDest[i][j]);
}
}
}
}
 

You can copy a single at a time........
