您好，我需要幫助將零錢排序?yàn)樾?shù)，如 25 美分、便士、鎳幣等。它說(shuō)可能有損轉(zhuǎn)換。這是我的代碼：public class Assignment04 { public static void main(String[] args) { Scanner stdin = new Scanner(System.in); System.out.println("Enter your amount"); long amount = stdin.nextLong(); long remainder = Math.round(amount * 100 ); long hundreds = (int) remainder / 10000; remainder = remainder % 10000; long fifties = (int) remainder / 5000; remainder = remainder % 5000; long twenties = (int)remainder / 2000; remainder = remainder % 2000; long tens = (int)remainder / 1000; remainder = remainder % 1000; long fives = (int)remainder / 500; remainder = remainder % 500; long ones = (int)remainder / 100; remainder = remainder % 100; long quarters = remainder / .25; remainder = remainder % .25; long dimes = (int)remainder / .10; remainder = remainder % .10; long nickels = (int)remainder / .5; remainder = remainder % .5; double pennies = (int) remainder; System.out.println(hundreds + "hundred/s"); System.out.println(fifties + "fiftie/s"); System.out.println(twenties + "twentie/s"); System.out.println(tens + "ten/s"); System.out.println(fives + "five/s"); System.out.println(ones + "one/s"); System.out.println(quarters + "quarter/s"); System.out.println(dimes + "dime/s"); System.out.println(nickels + "nickel/s"); System.out.println(pennies + "cent/s"); }}我試圖弄清楚如何刪除紅色下劃線，以便它可以正確運(yùn)行。我已經(jīng)完成了大部分工作，只是當(dāng)涉及到小數(shù)時(shí)我感到困惑。

您的余數(shù)字段似乎以美分表示。
$100 = 10000
$20 = 2000
$1 = 100
因此，四分之一應(yīng)為 25，一角應(yīng)為 10，五分鎳應(yīng)為 5。
還要更改此：
double pennies = (int) remainder;
對(duì)此：
long pennies = remainder;
修復(fù)掃描儀輸入的 amount 并刪除所有最終存儲(chǔ)在 long 中的行的 (int) 轉(zhuǎn)換：
public class Assignment04 {
public static void main(String[] args) {
Scanner stdin = new Scanner(System.in);
System.out.println("Enter your amount");
long remainder = Math.round(stdin.nextDouble() * 100 );
long hundreds = remainder / 10000;
remainder = remainder % 10000;
long fifties = remainder / 5000;
remainder = remainder % 5000;
long twenties = remainder / 2000;
remainder = remainder % 2000;
long tens = remainder / 1000;
remainder = remainder % 1000;
long fives = remainder / 500;
remainder = remainder % 500;
long ones = remainder / 100;
remainder = remainder % 100;
long quarters = remainder / 25;
remainder = remainder % 25;
long dimes = remainder / 10;
remainder = remainder % 10;
long nickels = remainder / 5;
remainder = remainder % 5;
long pennies = remainder;
System.out.println(hundreds + "hundred/s");
System.out.println(fifties + "fiftie/s");
System.out.println(twenties + "twentie/s");
System.out.println(tens + "ten/s");
System.out.println(fives + "five/s");
System.out.println(ones + "one/s");
System.out.println(quarters + "quarter/s");
System.out.println(dimes + "dime/s");
System.out.println(nickels + "nickel/s");
System.out.println(pennies + "cent/s");
}
}

你可以使用 int 。而不是長(zhǎng)。我希望這有幫助。謝謝
Scanner stdin = new Scanner(System.in);
int amount;
int remainder;
System.out.print("Enter amount:");
amount= (int) Math.round(stdin.nextDouble() * 100);
int hundreds= remainder / 1000;
if (hundreds > 0) {
remainder = remainder% 1000;
System.out.println(hundreds + "hundred/s");
}
int fifties = remainder / 1000;
if (fifties > 0) {
remainder = remainder% 1000;
System.out.println(fifties + "fiftie/s");
}
// number of twenties for remainder.
int twenties = change / 2000
if (twenties > 0) {
remainder= remainder % 2000; // this resets the value of remainder to
// the remainder after the twenties are
// calculated but only if there was at
// least enough to make one twenty
System.out.println(twenties + "twentie/s");
}
int tens = remainder / 1000;
if (tens > 0) {
remainder = remainder% 1000;
System.out.println(tens + " ten/s");
}
int fives = remainder/ 500;
if (fives > 0) {
remainder= remainder% 500;
System.out.println(fives + " five/s");
}
int ones = remainder/ 100;
if (ones > 0) {
remainder = remainder % 100;
System.out.println(ones + " one/s");
}
int quarters = remainder/ 25;
if (quarters > 0) {
remainder= remainder% 25;
System.out.println(quarters + " quarter/s");
}
int dimes = remainder/ 10;
if (dimes > 0) {
remainder = remainder % 10;
System.out.println(dimes + " dime/s");
}
int nickels = remainder/ 5;
if (nickels > 0) {
remainder= change % 5;
System.out.println(nickels + " nickel/s");
}
int pennies = remainder;
System.out.println(pennies + " cent/s");
}
}
