Java code
public static void main(String[] args) {
//        System.out.println(contain("dssd"));
        String s1 = "侵害人员：本地, 侵害人员：老年, 侵害人员：人大代表, 侵害人员：发廊妹, 侵害人员：1,";
        String s2 = "侵犯物品：一般物品, 侵犯物品：保险柜, 侵犯物品：1,";
        String s3 = "地点属性：高层楼宇, 地点属性：机关, 地点属性：银行, 地点属性：工厂, 地点属性：城中村, 地点属性：1,";
        String s4 = "作案时机：雨天, 作案时机：工作日, 作案时机：早晨, 作案时机：1,  ";
        String s5 = "入口出口：.门, 入口出口：1, ";
        s1 = s1.replaceAll(",(.*?)：", "、");
        s2 = s2.replaceAll(",(.*?)：", "、");
        s3 = s3.replaceAll(",(.*?)：", "、");
        s4 = s4.replaceAll(",(.*?)：", "、");
        s5 = s5.replaceAll(",(.*?)：", "、");
        System.out.println(s1);
        System.out.println(s2);
        System.out.println(s3);
        System.out.println(s4);
        System.out.println(s5);
