Java判斷Object對象類型的方法是什么？動力節(jié)點(diǎn)小編來告訴大家。

Object param = params.get(i);
   if (param instanceof Integer) {
    int value = ((Integer) param).intValue();
    prepStatement.setInt(i + 1, value);
   } else if (param instanceof String) {
    String s = (String) param;
    prepStatement.setString(i + 1, s);
   } else if (param instanceof Double) {
    double d = ((Double) param).doubleValue();
    prepStatement.setDouble(i + 1, d);
   } else if (param instanceof Float) {
    float f = ((Float) param).floatValue();
    prepStatement.setFloat(i + 1, f);
   } else if (param instanceof Long) {
    long l = ((Long) param).longValue();
    prepStatement.setLong(i + 1, l);
   } else if (param instanceof Boolean) {
    boolean b = ((Boolean) param).booleanValue();
    prepStatement.setBoolean(i + 1, b);
   } else if (param instanceof Date) {
    Date d = (Date) param;
    prepStatement.setDate(i + 1, (Date) param);
   }
