Program: How to convert String to signed decimal integer value?


Description:

By using Integer.parseInt() method, we can convert String to singned decimal integer value.


Code:
package com.java2novice.wrapper.integer;

public class MySignedParseInt {

	public static void main(String a[]){
		String number = "768";
		Integer i = Integer.parseInt(number);
		System.out.println("converted integer: "+i);
		number = "-786";
		i = Integer.parseInt(number);
		System.out.println("converted integer: "+i);
	}
}

Output:
converted integer: 768
converted integer: -786

What is fail-fast in java?
A fail-fast system is nothing but immediately report any failure that is likely to lead to failure. When a problem occurs, a fail-fast system fails immediately. In Java, we can find this behavior with iterators. Incase, you have called iterator on a collection object, and another thread tries to modify the collection object, then concurrent modification exception will be thrown. This is called fail-fast.
Famous Quotations
I don’t know the key to success, but the key to failure is trying to please everybody.
