如何在 Java 中将字符串转换为 int?
我试图弄清楚如何将其中包含整数的字符串转换为整数变量。
代码:
import java.util.Scanner;
public class main {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.println("Enter date of birth (MM/DD/YYYY):");
String DOB = input.next();
String month = DOB.substring(0, 1);
String day = DOB.substring(3, 4);
String year = DOB.substring(6, 9);
int month1 = month;
int age = 0;
//age = 2013 - DOB - 1;
int age2 = 0;
age2 = age + 1;
System.out.println("You are " + age + " or " + age2 + " years old");
}
}
我想把String month
, String day
, 和Sting year
变成整数。
