String replacement method of stencil MessageFormat.format (String pattern, Object ... arguments)

MessageFormat.format(String pattern, Object ... arguments)

MessageFormat.format(NewOrderConstant.PAY_SCHEMA,
        URLEncoder.encode(MessageFormat.format(NewOrderConstant.RESULT_SCHEME, String.valueOf(orderId)), HTTP.UTF_8),
        URLEncoder.encode(MessageFormat.format(NewOrderConstant.RESULT_SCHEME, String.valueOf(orderId)), HTTP.UTF_8),
        URIUtil.encodeQuery(shopBO.getShopName(), HTTP.UTF_8),
        this.toStringWithRemoveTrailingZeros(huiAmount),
        NewOrderConstant.BIZ_ORDER_TYPE_OEDER,
        String.valueOf(orderId),
        String.valueOf(shopId),
        noHuiAmount == null ? "0" : this.toStringWithRemoveTrailingZeros(noHuiAmount),
        (shopBO.getType() == ShopTypeCode.IntellRestaurant_PRE_PAY || shopBO.getType() == ShopTypeCode.HBT_PRE_PAY) ? 1 : 0,
        URLEncoder.encode("{supportVoucher:" + shopBO.getHuiType() + "}", HTTP.UTF_8));

String content = "ab, cc, {name}, {password}, ​​{DATE}, dd, ff";

String array[] = {userName, password, format.format(new Date())};
content = MessageFormat.format(content, array);

Explained as follows:

content needs to be replaced is in {} parameter, array stored in the array is to be replaced corresponding to the parameter; MessageFormat method used when the need for these parameters will be the number of correct matches, and to specify the sequence number, otherwise, matching error. This realization of replaceable parameters. Very simple, and very rigid.

MessageFormat: From java.text package;

We can open your own jdk source code to read his implementation.
