Java批量将文件中的段落替换成空格，根据指定分隔符换行（SQL示例）

public class Demo {
	public static void main(String[] args) {
		String s = "'133','153','180','181','189','177','130','131','132','155','156','145','185','186','176','134','135','136','137','138','139','150','151','152','158','159','182','183','184','157','187','188','147','178','170'";
		String str[] = s.split(",");
		StringBuilder sb = new StringBuilder();
		StringBuilder rs = new StringBuilder();

		int num = 15; // 15是分割段
		int yu = str.length % num;

		int a = 0;
		for (int i = 0; i < str.length; i++) {
			a++;
			sb.append(str[i] + ",");
			if (a == num) {
				a = 0;
				rs.append(sb + "\n");
				sb = new StringBuilder();
			}
		}
		sb = new StringBuilder();
		for (int i = yu; i > 0; i--) {
			sb.append(str[str.length - i] + ",");
		}
		rs.append(sb);
		System.out.println(rs.substring(0, rs.length() - 1));

		System.out.println("\n" + str.length + " : " + (rs.toString().split(",").length));
