Thread: Leading zeros

I am BSc(I.T) student. In last lecture sir give one assignment on java. In that assignment there is one program. The program is like write java program to add leading zeros to a number. I tried different way but not any of them work out. Can anybody help me to resolve this program?
Thanks in advanced.

According to me following is the very easy program to add leading zeros to a number. You have to just set that value into one variable then you have to transfer it another variable. After this you have to use append() method to do this.

String addZeross(Sting a)
{
int b=0;
k=a.length();
if ( b = 10 )
return c;
else
{
int d= 10 - b;
for (int k=0; b<=c; d++)
{c="0"+c;}
return c;
}
