如何在 Java 中将字符串转换为 int？
I am trying to figure out how to convert a string that has integers in it to an integer variable.
我想弄清楚如何将包含整数的字符串转换为整数变量。
Code:
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");
}
}
I want to turn String month, String day, and Sting yearinto integers.
我想把String month, String day, 和Sting year变成整数。

use
int month = Integer.parseInt(stringMonth);
利用
int month = Integer.parseInt(stringMonth);
