Converting datatype in Java

[bijayanib]

Hi All,

I came across a Java tips and would like to share with you. The tips is regarding "Converting datatype in Java". here is the few detail about the tips:

There are times while coding when we need to convert an entity of one datatype to another. For instance, in the following example, assigning an integer value to a string would throw exception, so what we would do instead is convert the integer into a string value.

integer to String :
int i = 42;
String str = Integer.toString(i);
or
String str = "" + i;


Hope you find it useful and of assistance.

Regards,
Bijayani

Another method of integer to string conversion in Java is:

String abc= String.valueOf(i);

I believe you should also be able to accomplish the same thing using explicit casting, the same way you can in PHP (although you rarely need to since PHP uses implicit casting):

int i = 42;
String phrase = "Life, the universe and everything = ";
System.out.println(phrase + (String) i)

Granted, yes, the + operator will actually call the toString method automatically

I think , String abc= String.valueOf(i);
