public class Test { public static void main(String ar[]) { Integer a = 10; Integer b =10; Integer c = 145; Integer d = 145; System.out.println(a==b); System.out.println(c==d); } }
7 10853solve this is my problem byte a=40,byte b=50 both add value is 90 this is with in range of byte... byte range is -128to 127.... why this pgm gives error like type mismatch.... package javapgms; public class byte1 { public static void main(String args[]) { byte a=40,b=50; byte c=a+b; System.out.println(c); } } note : dont use int k... a,b,c are in byte range... mind it..
