[英]indexOf() String Class Java
I need help with comparing an indexOf
from a string with an array of strings and display the correct matches. 我需要将字符串的
indexOf
与字符串数组进行比较并显示正确的匹配项时需要帮助。
public static void printvehicleMAKE(ServiceAppointment[] services, Scanner input){
System.out.print("Enter vehicle make: ");
String make = input.next();
String model = make.substring(0,3);
System.out.println(model);
boolean flag = false;
System.out.println("Details of all vehicles manufactured by " +make+" : ");
for (int i=0;i<6;i++) {
if(model.equalsIgnoreCase(services[i].getvehicleMAKEMODEL())){
System.out.printf("\n%10s%15s%20s", services[i].getregoNUMBER(),
services[i].getbuildYEAR(), services[i].getvehicleMAKEMODEL());
flag = true;
}
}
if(flag==false)
System.out.print("No service appointments were found for vehicles "
+ "made by " + make);
}
Example. 例。 If I enter "toyota" or "aston", I want it to compare the 1st/2nd character of the string and return the matches from the array of strings.
如果输入“ toyota”或“ aston”,我希望它比较字符串的第1/2个字符并从字符串数组返回匹配项。
Assuming that 假如说
services[i].getvehicleMAKEMODEL())
gives the full string as in "Toyota Camry" you must adjust your filter criteria. 给出完整的字符串,如“ Toyota Camry”中所示,则必须调整过滤条件。 Currently you compare
"to"
with "Toyota Camry"
. 当前,您将
"to"
与"Toyota Camry"
。 This does not match. 这不匹配。 So you should use this instead
所以你应该改用这个
model.equalsIgnoreCase(services[i].getvehicleMAKEMODEL().substring(0,3))
