Hi i have created multidimension array and accessed the values using for loop? how can we do using for-each loop?
class MultiArray
{
int arr[][];
public MultiArray()
{
arr = new int[][]{{1,2,3},{4,5,6,7},{8,9,10,11,12}};
}
public void forLoop()
{
for(int i=0;i<arr.length;i++)
{
for(int j=0;j<arr[i].length;j++)
{
System.out.print(arr[i][j]+" ");
}
System.out.println();
}
}
public static void main(String[] args)
{
MultiArray ma = new MultiArray();
ma.forLoop();
}
}

Your question is not clear. What do you need? Please rephrase!

Yet another copy of this same message. Don't cross-post!

Bartender will probably kill this thread.

class MyClass
{
int arr[][];
public MyClass()
{
arr = new int[][]{{1,2,3},{4,5,6,7},{8,9,10,11,12}};
}
public void forLoop()
{
for(int i: arr[0])
{
System.out.print(i);
}
for(int j:arr[1])
{

System.out.println(j);
}
for(int k:arr[2])
{
System.out.println(k);
}
}
public static void main(String[] args)
{
MyClass ma = new MyClass();
ma.forLoop();

}
}

I think this is one of the ways to print the multidimensional array using for-each loop

But if your array had equal no of rows and cols then you could try this.
public class MyClass
{
public static void main(String args[])
{
int[][] a = { {1,2,3} , {4,5,6} , {10,11,12} };
for(int[] i : a)
{


System.out.println(i[0]+" "+i[1]+" "+i[2]);
}
}
}

there are also some new APIs added in Arrays class for doing such operation
have a look at those.
