如何将int 型数组转换成byte型数组

Answer 1

int转byte数组
public static byte[]
intToBytes2(int n){
byte[] b = new byte[4];

for(int i = 0;i < 4;i++)

{

b[i]=(byte)(n>>(24-i*8));

}

return b;
}

byte转换为int
public static int byteToInt2(byte[] b)
{

int mask=0xff;

int temp=0;

int n=0;

for(int i=0;i<b.length;i++){

n<<=8;

temp=b[i]&mask;

n|=temp;

}

return n;

}
