Ввод/вывод в Groovy

[leprekod]

Вот более пристойная реализация цикла:

Map rim_arab = [ "I":1, "V":5, "X":10, "L":50, "C":100, "D":500, "M":1000]
BufferedReader br = new BufferedReader(new InputStreamReader(System.in)) 
print "Vvedite Rim = "
Rim = br.readLine()  
while( Rim != "n") {           
f = Rim.replace("IV", "IIII").replace("IX", "VIIII").replace("XL", "XXXX").replace("XC", "LXXXX").replace("CD", "CCCC").replace("CM", "DCCCC")
Arab = 0; for(i in f) { Arab = Arab + rim_arab[i]}
print "Arab = "; println Arab
print "Vvedite Rim = "
Rim = br.readLine()
                   }

Но, то что мне действительно надо - это код осуществляющий бесконечный цикл, и выход из этого цикла по достижению истинности условия!...

Исправление и изменение в arab_rim:

....................................................................................
case 0: r = ""; break
                        }; ++i; l = l + r}
                         S = l.reverse().join(); print "Rim = "; println S

Правильный цикл:

Map rim_arab = [ "I":1, "V":5, "X":10, "L":50, "C":100, "D":500, "M":1000]
BufferedReader br = new BufferedReader(new InputStreamReader(System.in)) 
while( 1) {  
print "Vvedite Rim = "
Rim = br.readLine(); if(Rim == "n") {break}        
f = Rim.replace("IV", "IIII").replace("IX", "VIIII").replace("XL", "XXXX").replace("XC", "LXXXX").replace("CD", "CCCC").replace("CM", "DCCCC")
Arab = 0; for(i in f) { Arab = Arab + rim_arab[i]}
print "Arab = "; println Arab
                   }

Некоторое усовершенствование:

def rimarab(Rim) {
Map rimArab = [ "I":1, "V":5, "X":10, "L":50, "C":100, "D":500, "M":1000]
f = Rim.replace("IV", "IIII").replace("IX", "VIIII").replace("XL", "XXXX").replace("XC", "LXXXX").replace("CD", "CCCC").replace("CM", "DCCCC")
Arab = 0; for(i in f) { Arab = Arab + rimArab[i]}                 
                 }
BufferedReader br = new BufferedReader(new InputStreamReader(System.in))
while( 1) { 
print "Vvedite Rim = "
Rim = br.readLine(); if(Rim == "n") {break}
rimarab(Rim)      
print "Arab = "; println Arab 
          }

[leprekod]

def Vvod () {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in))
print "Vvedite Rim = "; Rim = br.readLine()
            }
def rimarab (Rim) {
Map rimArab = [ "I":1, "V":5, "X":10, "L":50, "C":100, "D":500, "M":1000]
f = Rim.replace("IV", "IIII").replace("IX", "VIIII").replace("XL", "XXXX").replace("XC", "LXXXX").replace("CD", "CCCC").replace("CM", "DCCCC")
Arab = 0; for(i in f) { Arab = Arab + rimArab[i]}
                  }
def Vivod () { print "Arab = "; println Arab}
while (1) { 
Vvod (); if(Rim == "n") {break}
rimarab (Rim)      
Vivod ()  }
