공용 클래스 문자열 { 공공 정적 무효 메인 (문자열 [] 인수) {

String str= "45"; 
String op=addToString(str, ":"); 
System.out.println(op); 
} 
static String addToString(String str, String ins) { 
    if(str.length()<=2) 
    { 
     str="00"+str; 
    } 
    int i = str.length()-(str.length()-2); 
    return str.substring(0, i) + ins + str.substring(i); 
}
