1. Concept
Create an array in memory and assign some default values to it.
2. Common initialization methods
(1) Dynamic initialization (specify length)
(2) Static initialization (specify content)
3. Static initialization
In addition to using the new keyword to generate an array, you can also allocate space and assign values to array elements directly while defining the array.
// 静态初始化
int[] iStaticArr = { 5, 2, 0 };
LOLHero[] staticHeros = new Hero[] {
new LOLHero("艾希","女"),
new LOLHero("盖伦","男"),
new LOLHero("挖掘机","未知")
};
4. Dynamic initialization
When initializing, the programmer only specifies the length of the array, and the system assigns an initial value to the array elements.
arrayName = new type[length];
5. Default initialization
We statically initialize the array when defining it, and we can use a more concise method.
type[] arrayName = {element1 , element2 , ...};The above is the detailed content of Java array initialization example analysis. For more information, please follow other related articles on the PHP Chinese website!
