The boolean data type indicates whether the value of an expression is either true or false. Therefore, a variable or expression which is declared as boolean type can use these two keywords. Syntax : boolean var_name; Example : boolean a; a=true; Or a=false;
布尔数据类型指示表达式的值是真还是假。因此，声明为布尔类型的变量或表达式可以使用这两个关键字。语法：boolean var_name; 示例：布尔值a；a=真；或 a=false;
