JAVA converts boolean to int. Convert int to boolean

The conversion of true, false and 1, 0 in the programming language
C ++ true and false code demonstration

True, false and 1, 0 conversion principle

Boolean is converted to the number
false is 0, true is 1 the
number is converted to Boolean
0 is false; non-zero is true

Java does not support direct forced transfer

1. Convert Boolean to number-false is 0, true is 1

The only way: Sanmu statement

 int myInt = myBoolean ? 1 : 0;

Sample code:

 boolean myBoolean = true;
 int myInt = myBoolean ? 1 : 0;
 System.out.println(myInt); //输出1
 myBoolean = false;
 myInt = myBoolean ? 1 : 0;
 System.out.println(myInt);  //输出0

Second, the number is converted to Boolean-0 is false; non-zero is true

method one:

 boolean myBoolean = myInt != 0;

Sample code:

 int myInt= 2;
 boolean myBoolean = myInt!= 0;
 System.out.println(myBoolean); //输出为true
 myInt= 0;
 myBoolean = myInt!= 0;
 System.out.println(myBoolean); //输出为false

Method 2: Trinocular statement

 int a = 1; //带转化int整数
 boolean result = (a==0)?false:true; //转化语句

Sample code:

 int myInt = 2; //被转化int整数
 boolean myBoolean = (myInt == 0) ? false : true; //转化语句
 System.out.println(myBoolean); //输出为true
 myInt = 0; //被转化int整数
 myBoolean = (myInt == 0) ? false : true; //转化语句
 System.out.println(myBoolean); //输出为true
