在定义一个数组c，将a，b的值赋给c

Question

静态定义两个数组
int[ ] a={11,22,33,44,55};
int b[ ]={12,45,78,65};
在定义一个数组c，将a，b的值赋给c

Answer 1

public class t7 {
    public static void main(String[] args) {
        int[] a={11,22,33,44,55};
        int[] b={12,45,78,65};

        int[] c=new int[a.length+b.length];
        System.arraycopy(a, 0, c, 0, a.length);
        System.arraycopy(b, 0, c, a.length, b.length);
        for (int i = 0; i < c.length; i++) {
            System.out.println(c[i]);
        }
    }
}
