int to boolean Java

int to boolean Java


After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast int to boolean.

The data type boolean is incompatible for converting into any other data type. That is, a boolean value cannot be converted (or assigned to) into any other data type like char, int, double, short etc. The maximum permitted is one boolean can be assigned to another boolean.

Following are not permitted.

int i1 = 10;
boolean b = i1; // error, int to boolean

boolean b = true;
int i1 = b; // error, boolean to int

char ch = ‘A’;
boolean b =ch; // error, char to boolean

Following is permitted (boolean assignment).

boolean b = true;
boolean b1 = b; // permitted
System.out.println(b1); // prints true

The keyword boolean is used in comparison operations.

Let us write an example on int to boolean and find the compiler error message.
