Java数组初始化方式

Java数组初始化

1. 逐个初始化

int[] array = new int[3];
for (int i = 0; i < array.length; i++) {
    array[i] = i + 2;
}

for (var elem : array) {
    System.out.print(elem + " ");
} // 2 3 4 

2.声明时初始化

String[] array = new String[]{"zhao", "qian", "sun", "li", "zhou"};

for (var elem : array) {
	System.out.print(elem + " ");
} //zhao qian sun li zhou 

int[] array = { 1, 2, 3, 4, 5 }; // 可以不用写new
