java中如何给字符串⾼位补0_AndroidJava字符串或进制⾼位

补0

释放双眼，带上⽿机，听听看~！

字符串补位⽅法

/**

*str原字符串

*strLength字符串总长

**/

publicstaticStringaddZeroForNum(Stringstr,intstrLength){

intstrLen=();

if(strLen

while(strLen

StringBuffersb=newStringBuffer();

("0").append(str);//左补0

//(str).append("0");//右补0

str=ng();

strLen=();

}

}

returnstr;

}

进制补位⽅法

publicstaticStringten2Hex1(intnum){

//num=120000000;

//StringstrHex1=tring(num).toUpperCa();

StringstrHex1=("%02x",num).toUpperCa();//不⾜两位⾼位补0

returnstrHex1;

}

publicstaticStringten2Hex2(intnum){

//StringstrHex1=tring(valueTen).toUpperCa();//⾼位不⽤补0

StringstrHex2=("%08x",num).toUpperCa();//⾼位补0

returnstrHex2;

}
