I'll give a simple code here. Here the output developed by using characters. So have to think about a way to concatenate those characters and make as strings.

Code:

public class StringTest
{
public static void main(String[] arguments)
{
String s1 = "abc";
String s2 = "123";
int s1Len = s1.length();
int s2Len = s2.length();

for(int temp1 =0;temp1 < s1Len;temp1++)
{
	for(int temp2 = 0;temp2 < s2Len;temp2++)
	{
	char ch1=s1.charAt(temp1);
	System.out.print(ch1);
	char ch2=s2.charAt(temp2);
	System.out.println(ch2);
	}
}
}
}

Check there how final strings are obtained using print() and println()
