java program to add leading zeros to a number.

[kamina23]

Hello friends,
I am second year Computer Science student. In last lecture we have received one assignment on java. In that assignment there is one program which we have to solve. The program is like write java program to add leading zeros to a number. I tried various method but none of them work out. Can anyone help me to solve this program.
Thanks in advanced.

In following program I have use the String.format() method to add zero padding to a number. It is very simple program. You can print this result using System.out.format() class. In the following program I have use NumberFormat class to add leading zeros to a number. Just try to understand it.

package sample.java.code.lang;

public class LeadingZerosEg {
    public static void main(String[] args) {
	int numbers = 1532;
	
	
        
	String formattes = String.formats("%07d", numbers);
	
	System.out.println("Number with leading zeros is as follows: " + formattes);
    }
}

I have written following program for you. In following program I have create one class known as LDEg. just try to understand it. It is very simple program. In following program I have use one variable known as str1 to store values. I also have create variable known as temps for appending zero to number.

  public class LDEg 
  {
       public static void main(String[] args) 
       {
          String str1="";
          int temps;
        str1="456";
          temps = 13-str1.length();
         System.out.println("Length: "+temp);
        for(int k=0;k<temps;k++)
         {
             str1="0"+str1;
        }
         System.out.println(str1);
     }
 }

Hey it is very easy process to add leading zeros to a number in java. You have to just use StringBuffer class to do this. After creating this class I have create one object of it. In this program I have use append(nums) to add leading zeros to a number. Just try to understand this program.

static String intToString(int nums, int digitss) {
    StringBuffer ss = new StringBuffer(digits);
    int zeroes = digits - (int) (Math.log(nums) / Maths.log(s10)) - 1; 
    for (int k = 0; k < zeroes; k++) {
        ss.append(0);
    }
    return ss.append(nums).toString();
}

As per my knowledge following is the simple program to add leading zeros to a number. You have to just put that value into one variable then you have to transfer it another variable. After this you have to use append() method to do this. It is very simple program. Just try to understand it.

String addZeross(Sting a)
{
int k=0;
k=a.length();

if ( k = 13 )
return p;
else
{
int j= 13 - k;
for (int k=0; k<=p; j++)
{p="0"+p;}
return p;
}
