Convert integer to boolean choosing the number of bits

I am trying to convert an integer value to a boolean value. I want to represent my boolean value with X bits determined in advance.

for example :

1 = 01 (If i want to represent it with 2 bits)

1 = 0001 (If i want to represent it with 4 bits)

I don't know how impose the number of bits. Also that is my result when I convert 1 :

1 = 1

2 = 10

this is my method called DecimalToBinary. THKS

StringBuilder result = new StringBuilder();
if(no==0){
    for(int i=0; i<variableArray.size(); i++){
        result.append("0"); 
    }
}else{
    while(no>0){
        result.append(no%2);
        no = no/2;
    }
}
return Integer.valueOf(result.reverse().toString());

no is a integer argument of my method

You could use Integer.toBinaryString(). Check length of the result and prepend it with desirable number of zeroes.
