Try this,

试试这个，

byte[] infoBin = null;
    infoBin = "Java".getBytes("UTF-8");
    for (byte b : infoBin) {
        System.out.println("c:" + (char) b + "-> "
                + Integer.toBinaryString(b));
    }

Try this

试试这个

  byte[] bytes = str.getBytes(charSetName);

this encodes str into a sequence of bytes using the named charset, storing the result into a byte array.

这使用命名的字符集将 str 编码为字节序列，并将结果存储到字节数组中。

string have getBytes()method.

字符串有getBytes()方法。

  str.getBytes();
