Conversion from 12 hours time to 24 hours time in java

Question

In my app, I have a requirement to format 12 hours time to 24 hours time. What is the method I have to use?

For example, time like 10

Answer 1

Using LocalTime in Java 8, LocalTime has many useful methods like getHour() or the getMinute() method,

For example,

LocalTime intime = LocalTime.parse(inputString, DateTimeFormatter.ofPattern("h:m a"));
String outtime = intime.format(DateTimeFormatter.ISO_LOCAL_TIME);

In some cases, First line alone can do the required parsing
