Convert a String to int


Use the static method parseInt of the Integer class to convert
a String to an int as below:


 

  public void convertStringToInt() {
    
    String sValue = "5";
    int iValue = 0;
    
    try {
      iValue = Integer.parseInt(sValue);
    }
    catch (NumberFormatException ex) {
      System.out.println("The String does not contain a parsable integer");
    }
    
    //Additional code goes here...

  }


Alternatively you can pass a String to the Integer class constructor
and call the intValue-method of the object:


  public void convertStringToInt() {
    
    String sValue = "5";
    int iValue;
    
    try {
      iValue = new Integer(sValue).intValue();
    }
    catch (NumberFormatException ex) {
      System.out.println("The String does not contain a parsable integer");
    }

    //Additional code goes here...

  }
