三种字符数组合并的方法

public static String[] getOneArray() {
String[] a = { "0", "1", "2" };
String[] b = { "0", "1", "2" };

String[] c = new String[a.length + b.length];

for (int j = 0; j < a.length; ++j) {
c[j] = a[j];
}

for (int j = 0; j < b.length; ++j) {
c[a.length + j] = b[j];
}

return c;
}

public static Object[] getTwoArray() {
String[] a = { "0", "1", "2" };
String[] b = { "0", "1", "2" };

List aL = Arrays.asList(a);
List bL = Arrays.asList(b);

List resultList = new ArrayList();
resultList.addAll(aL);
resultList.addAll(bL);

Object[] result = resultList.toArray();
return result;
}

public static String[] getThreeArray() {
String[] a = { "0", "1", "2", "3" };
String[] b = { "4", "5", "6", "7", "8" };
String[] c = new String[a.length + b.length];
System.arraycopy(a, 0, c, 0, a.length);
System.arraycopy(b, 0, c, a.length, b.length);
return c;
}

1.两个字符数组合并的问题

public String[] getMergeArray(String[] al,String[] bl) {
String[] a = al;
String[] b = bl;
String[] c = new String[a.length + b.length];
System.arraycopy(a, 0, c, 0, a.length);
System.arraycopy(b, 0, c, a.length, b.length);
return c;
}

2.字符数组和整形数组合并问题

public int[] getIntArray(int[] al,String[] bl) {
int[] a = al;
String[] b = bl;
int[] ia=new int[b.length];
for(int i=0;i
