我有一个带有航班号的文本文件,我的目标是让这个方法搜索该文本文件,然后用#34;航班号"打印出所有行。
public static void print_flight(int rcount,int[]reservation_code,int[]fl_number,String[]last_name,String[]first_name,String[]seat_type,double[]seat_cost)
{
int i, total=0;
String search_flight = "";
String output = "Enter the Flight Number you are searching for";
search_flight = JOptionPane.showInputDialog(null,
output, " ",
JOptionPane.QUESTION_MESSAGE);
for (i = 0; i <=rcount; ++i) {
//CHECK flight number
if(fl_number[i].equals(search_flight))//ERROR IS HERE
{
total+=fl_number[i]; //not sure if that is right
System.out.println(reservation_code[i]+" "+fl_number[i]+" "+last_name[i]+" "+first_name[i]+" "+seat_type[i]+" "+seat_cost[i]);
}
}
}
答案 0 :(得分:1)
使用Integer.parseInt将其转换为int值,然后使用==
int flight_number = Integer.parseInt(search_flight); //convert to int
if(fl_number[i] == flight_number)//compare two ints

通常没有对航班号执行算术,所以事情应该是字符串数组。
答案 2 :(得分:0)
fl_number是一个int数组 和 search_flight是一个String,您应该将其解析为int以使用fl_number
所以,fl_number [i] .equals(search_flight)
- &GT; fl_number [i] == Integer.Parse(search_flight)
