The default value of char type is \u0000, and if we want to initialize a char value with the default value, just create it as an instance variable and let the Java compiler do the rest of the work. public class SimpleTesting { char ch; // no initialization public static void main(...

To iterate over the character array, you use thefor eachloop. In this type of loop, no initialization of counter value or condition is to be explicitly specified. Instead, it declares a datatype variable and the collection over which the data variable is to iterate. Finally, in the loop ...
基本数据类型的局部变量存放在 Java 虚拟机栈中的局部变量表中,基本数据类型的成员变量(未被static修饰 )存放在 Java 虚拟机的堆中。包装类型属于对象类型,我们知道几乎所有对象实例都存在于堆中。 相比于对象类型, 基本数据类型占用的空间非常小。 7.包装类型的缓存机制# ...
