数组元素的初始化

直接上代码 ，char的初始化值是'\u0000'

public class TestArray {
	public static void main(String[] args) {
		int a[] = new int[5];
		byte b[] = new byte[5];
		short c[] = new short[5];
		long d[] = new long[5];

		float e[] = new float[5];
		double f[] = new double[5];
		char g[] = new char[5];

		boolean h[] = new boolean[5];
		Object i[] = new Object[5];
		String j[] = new String[5];
		System.out.println("int数组初始值:" + a[0]);
		System.out.println("byte数组初始值:" + b[0]);
		System.out.println("long数组初始值:" + d[0]);
		System.out.println("short数组初始值:" + c[0]);
		System.out.println("float数组初始值:" + e[0]);
		System.out.println("double数组初始值:" + f[0]);
		System.out.println("char数组初始值:" + g[0]);
		System.out.println("boolean数组初始值:" + h[0]);
		System.out.println("object数组初始值:" + i[0]);
		System.out.println("String数组初始值:" + j[0]);

	}
}
