Description

The list of methods to do Integer to Binary are organized into topic(s).

Method

byte[]itob(int i, int j)
Creates a byte representation of the first argument 
byte[] res = new byte[j];
for (int n = j - 1; n >= 0; n--) {
    res[n] = (byte) ('0' + (i % 10));
    i = i / 10;
return res;
intItoB(int x)
Ito B 
return (x & 0x000000ff);
byte[]iToB(int[] intVals)
i To B 
byte[] byteVals = new byte[intVals.length];
for (int i = 0; i < byteVals.length; i++) {
    byteVals[i] = (byte) intVals[i];
return byteVals;
Stringitob(long integer, int[] arr)
Converts a binary number, the number required, and the number of bits desired output (here 26) Store the result in the overall picture "bit2" 
for (int i = 0; i < arr.length; i++) {
    if ((integer / power2(arr.length - 1 - i)) == 1) {
        integer -= power2(arr.length - 1 - i);
        arr[i] = 1;
    } else
        arr[i] = 0;
StringBuilder sb = new StringBuilder();
