Java 进制间的转换

//十进制转二进制String binaryStr = Integer.toBinaryString(20);System.out.println(binaryStr);//十进制转八进制String octalStr = Integer.toOctalString(20);System.out.println(octalStr);//十进制转十六进制String hexStr = Integer.toHexString(20);System.out.println(hexStr);//二进制转十进制Integer binaryDecimal = Integer.valueOf(binaryStr,2);System.out.println(binaryDecimal);//八进制转十进制Integer octalDecimal = Integer.valueOf(octalStr,8);System.out.println(octalDecimal);//十六进制转十进制Integer hexDecimal = Integer.valueOf(hexStr,16);System.out.println(hexDecimal);
