What does these statement mean:

***Interning also happens for :

*All Boolean values (true and false)
*All Byte values
*All Character values from \u0000 to \u007f (i.e. 0 to 127 in decimal)
*All Short and Integer values from -128 to 127

I have checked the API, there is no intern() method in Byte,Short,Boolean,Integer and Character classes.

This is from the Java Language Specification.

If the value p being boxed is true, false, a byte, a char in the range \u0000 to \u007f, or an int or short number between -128 and 127, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2.
 
No. No. No. No. Changed my mind. Wanna come down. To see this tiny ad:
