Java string with operator is converted to long type

Because the project needs to configure a refresh time in the configuration file, the data taken out of the configuration file is definitely a string, and then the string with the operator is converted to a long type. The specific code is as follows:

In configuration file system.properties:

1 reflash_time = (2*60*1000)

The Java code takes out the value:

1  Public Static Final String reflashtime = "Reflash_time"; 2  3  Public String reflashtime; 4  5 reflashtime = Prop.getproperty (reflashtime). Trim ();

The string is split by *, the number is saved in an array, and then multiplied to get its value:

1 string[] Reflash = Reflashtime.split ("\\*"2  3 for (int i = 0; i < reflash.length; i++) {4     reflashtime *= long.parselong (Reflash[i]); 5 }6  7 System.out.println (reflashtime);

This enables the conversion of a string with an operator to an integral type.
