In Java to convert a String type to int, you need to use the parseint () method in the Integer class or The ValueOf () method for conversion.Example 1:
123456
Stringstr="123";try{int a=Integer.parseInt(str);}catch(NumberFormatExceptione){e.printStackTrace();}
Example 2:
123456
Stringstr="123";try{int b=Integer.valueOf(str).intValue()}catch(NumberFormatExceptione){e.printStackTrace();}

Pseudo-Arrays (class arrays): You cannot call an array method directly or expect any special behavior for the length property, but you can still traverse them with a true array traversal method. Typically, the argument parameters of a function, as well as calls to Getelementsbytagname,document.childnodes, are all returned nodelist objects are pseudo-arrays. You can use Array.prototype.slice.call (Fakearray) to convert an array to a true array object.W
