反轉字符串數組

 

網上的人寫了兩個

 

public static void main(String[] args) {
		String ar[] = new String[]{"A","B","C"};
		String temStr = "";
		for(int i=ar.length; i > 0;i--){
			temStr+=ar[i-1];
		}
		System.out.println(temStr);
	}

 

 

public static void main(String[] args) {
		String testStr = "abcdefghijklmnopqrst";
		StringBuffer sb = new StringBuffer();
		for (int i = testStr.length() - 1; i >= 0; i--) {
			sb.append(testStr.charAt(i));
		}
		System.out.print(sb.toString());
	}

 

public static void main(String[] args){
		
		String[] aaa={"a","b","c","d"};
		int s=aaa.length;
		String[] bbb=new String[s];
		for(int i=0;i<s;i++){
			bbb[i]=aaa[s-i-1];
		}
		System.out.println(bbb.toString());
	}
