java语言将大数组拆分成小数组示例

//定义一个长度为X的数组
		String[] all = new String[10]; 
		for (int i = 0; i < 10; i++) {
			all[i]="组"+i;
		}
		//定义每个小数组的长度
		int SMS_GROUP_NUMER = 3;
		

		int length = all.length;
		int num = length / SMS_GROUP_NUMER;
		num = length % SMS_GROUP_NUMER != 0 ? num + 1 : num;
		System.out.println(num + " 取整" + (length % SMS_GROUP_NUMER == 0));
		
		//按照最大长度的小数组分组
		for (int j = 0; j < num - 1; j++) {
			String[] s = new String[SMS_GROUP_NUMER];
			for (int i = 0; i < SMS_GROUP_NUMER; i++) { s[i] = all[i + j * SMS_GROUP_NUMER]; System.out.print("大数组：all["+(i + j * SMS_GROUP_NUMER) + "] -> 小组：s[" + i
						+ "]" + ": [" + s[i] + "];  ");
			}
			System.out.println("##");
		}

		
		int roundFigure = length % SMS_GROUP_NUMER!=0?length % SMS_GROUP_NUMER:SMS_GROUP_NUMER;
		System.out.println(roundFigure+ " ### " + length);
		
		//按照多出来的数据进行分组
		String[] extra = new String[roundFigure];
		for(int j= 0;j<roundFigure;j++){ extra[j]= all[j+(num-1)*SMS_GROUP_NUMER]; System.out.println("大数组：all[" + (j+(num-1)*SMS_GROUP_NUMER)+ "] -> 小组: extra_s["+j+"] : ["+extra[j]+"]");
		}
		System.out.println(SMS_GROUP_NUMER+(SMS_GROUP_NUMER)*(length % SMS_GROUP_NUMER)+"---------------");
