Savol-javob: Java'da Stringni int ga qanday qilib to'g'ri aylantirish mumkin?

int x = 5;
String text = "X=" + x;

Misol

int i = Integer.parseInt (myString);

public class JavaStringToIntExample
{
  public static void main (String[] args)
  {
    // String s = "fred"; // use this if you need to test the //exception below
String s = "100";

    try
    {
      // this is where String is converted to int
      int i = Integer.parseInt(s.trim());

      // display the value after conversion
      System.out.println("int i = " + i);
    }
    catch (NumberFormatException nfe)
    {
      System.out.println("NumberFormatException: " + nfe.getMessage());
    }
  }

Munozara

int i = Integer.parseInt (s.trim ())

• Integer.toString (int i)intJava satrlariga aylantirish uchun ishlatiladi .
• StringAgar ob'ektni ob'ektga aylantirmoqchi bo'lsangiz Integer(ibtidoiy sinf o'rniga int), . o'rniga valueOf ()sinfdagi usuldan foydalaning .IntegerparseInt ()
• Agar siz satrlarni qo'shimcha ibtidoiy Java maydonlariga aylantirishingiz kerak bo'lsa, shunga o'xshash usullardan foydalaning Long.parseLong ().
