Append/join (bit shift) one binary value before another in Java -


i want able 'insert/append' 1 binary after another. int variables @ moment.

int = 1; int j = 4;

i want bit shift left 3 i add values together.

for example,

i binary: 1 (1) j binary: 100 (4)  result: 1100 (12) 

public static int appendbinary(int i, int j) {     string istr = integer.tobinarystring(i);     string jstr = integer.tobinarystring(j);     string binary = istr + jstr;     return integer.parseint(binary, 2); }

this method converts , j binary, subs before j, , converts result int. hope helps!
