String-format Style Use

First, let's look at the following code

protectedString calcu1 () {StringBuffer RESULTB=NewStringBuffer (); String Str=NULL; STR= String.Format ("hi,%s", "Wang Li"); Resultb.append (str+ "|"); STR= String.Format ("hi,%s:%s.%s", "Wang Nan", "Li Li", "Wang Zhang"); Resultb.append (str+ "|"); STR= String.Format (locale.us, "%" + 3 + "." + 4 + "G",                136985021.96584239551); Resultb.append (str+ "|"); SimpleDateFormat format=NULL; if(Iszh ( This) ) {format=NewSimpleDateFormat ("yyyy mm month DD Day"); } Else{format=NewSimpleDateFormat ("Yyy-mm-dd"); } STR= Format.format (NewDate (1000000000*2000l)); Resultb.append (str+ "|"); STR=getresources (). getString (R.string.test); STR= String.Format (str, "yy")); Resultb.append (str+ "|"); STR=getresources (). getString (R.string.test1); STR= String.Format (str, "Henan", "Xiayi", 33); Resultb.append (str+ "|"); STR=resultb.tostring (); returnstr; }

The resource files are as follows

<?XML version= "1.0" encoding= "Utf-8"?><Resources>    <stringname= "Test">My name is: \ "%1$s\"</string>    <stringname= "Test1">I come from: \ "%1$s\" province, \ "%2$s\" county, this year \ "%3$d\" years old</string></Resources>

The results of the operation are as follows

The above is actually mainly related to the following two points of knowledge
