『壹』 一算法题java实现，有一分钱，两分钱，五分钱，加起来等于10元钱。有多少种方法，并打印出来高手指教
一共50401组数据
public class ABC {
public static void main(String args[]) {
final int total = 1000;/穗渣/一共1000分
int count = 0;
for(int one = 0; one <= total / 1; one++){//察好1分钱数目
for(int two = 0; two <= total / 2; two++){//2分钱数目
for(int five = 0; five <= total / 5; five++){//5分钱数目
if(one*1 + two*2 + five *5 == total){
System.out.println("1*" + one + "败族铅 + 2*" + two + " + 5*" + five + "= 1000" );
count++;
}
}
}
}
System.out.println("Total possible " + count + " group!");
}
}
------------------
。。。。。
1*996 + 2*2 + 5*0= 1000
1*998 + 2*1 + 5*0= 1000
1*1000 + 2*0 + 5*0= 1000
Total possible 50401 group!
『贰』 Java定义一个表示人民币的类Money，
public class Money {
private int yuan;
private int jiao;
private int fen;
public Money(int yuan,int jiao, int fen){
this.yuan=yuan;
this.jiao=jiao;
this.fen=fen;
}
public void show(){
System.out.printf("%d元回%d角%d分",yuan,jiao,fen);
}
public static void main(String[] args) {
答Money m=new Money(4,5,6);
m.show();
}
}
『叁』 JAVA程序 输入一串数字如12341289.23，输出万千百十元角分。高手帮忙！谢谢
//将人民币金额转换为大写
function upDigit(n){
var fraction = ["角","分"];
var digit = ["零","壹","贰","叁","肆","伍","陆","柒","捌","玖"];
var unit = [["元","万","亿"],["","拾","佰","仟"]];
var head = n<0?"负":"";
n = Math.abs(n);
var s = "";
for(var i=0; i<fraction.length; i++){
s += (digit[Math.floor(n*10*Math.pow(10,i))%10]+fraction[i]).replace(/零./,"");
}
s = s||"整";
n = Math.floor(n);
for(var i=0; i<unit[0].length && n>0; i++){
var p = "";
for(var j=0; j<unit[1].length && n>0; j++){
p = digit[n%10] + unit[1][j]+p;
n = Math.floor(n/10);
}
s = p.replace(/(零.)*零$/,"").replace(/^$/,"零") + unit[0][i] + s;
}
return head + s.replace(/(零.)*零元/,"元").replace(/(零.)+/g,"零").replace(/(^整$)/,"零元整");
}
