java三种字符数组合并的方法

java三种字符数组合并的方法 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
