Parsing means we are analyzing an object specifically. For example, when we enter some keywords in a search engine, they parse the keywords and give back results by searching for each word. So it is basically taking a string from the file and processing it to extract the information we want.
Example of parsing using indexOf to calculate the position of a string in another string:
String s="What a Beautiful day!";
int i=s.indexOf("day");//value of i would be 17
int j=s.indexOf("be");//value of j would be -1
int k=s.indexOf("ea");//value of k would be 8
paresInt essentially converts a String to a Integer.
String s="9876543";
int a=new Integer(s);//uses constructor
System.out.println("Constructor method: " + a);
a=Integer.parseInt(s);//uses parseInt() method
System.out.println("parseInt() method: " + a);
Output:
Constructor method: 9876543
parseInt() method: 9876543
