Automatic conversion of Java data types, with casts

I. Automatic conversion of data types

 Public classtest{ Public Static voidMain (string[] args) {intA = 1; Doubleb = 1.5; DoubleA_b_count = a+b;//when integral and double are added, the result is automatically converted to a double-precision typeString C= "Ling"; Chard = ' Morning '; CharE = ' good '; String c_d_e_content= C+d+e;//when the character type is added to the string type, the result is automatically converted to a string typeSystem.out.println (A_b_count);    System.out.println (c_d_e_content); }}

Ii. Coercion of data types

 Public class test{    publicstaticvoid  main (string[] args) {        int    a    =    (int) 10.2;    // Casting Double-type data to reshape        Double    b    =    (double) ten;    // To cast data of an integral type to a double type         System.out.println (a);        System.out.println (b);    }}

An int and a double can be forced to convert each other.

Char and string types cannot be forced to convert to and from each other.
