java String str = "true"; Boolean bool = Boolean.valueOf(str); System.out.println(bool);输出true 3.使用逻辑判断:我们可以使用if语句或三元运算符来判断条件并将其转换为布尔类型。以下是一个示例: java int num = 5; boolean bool = (num > 0) ? true : false; System.out.println(bool);输出...
java String str = "true"; boolean result = convert.ToBoolean(str); 在这个例子中,我们将一个字符串"true"传递给convert.ToBoolean方法,它会将非空的字符串转换为true,将空字符串转换为false。所以这个例子中的result将会是true。 通过以上几个例子,我们可以看到convert.ToBoolean方法可以接受不同类型的参数,并...
