How to execute native rhythm out commands from JAVA
Though it’s non recommended simply to a greater extent than or less fourth dimension it’s popular off necessary to execute native operating organisation or rhythm out ascendence from JAVA, particularly if y'all are doing to a greater extent than or less variety of reporting or monitoring materials as well as required information tin easily endure institute using native command. This is non advised though because hence y'all volition lose platform independence which is why nosotros generally used JAVA.
Anyway if y'all no choice as well as y'all desire to execute native commands from JAVA hence its proficient to know that how nosotros tin produce it, many of y'all belike know this simply for those who don't know as well as bring never done it nosotros volition run into through an example.
Suppose y'all desire to execute "ls" ascendence inwards Linux which listing downwards all the files as well as directory inwards a folder as well as y'all desire to produce it using JAVA.
In JAVA nosotros bring a cast called "java.lang.Runtime" which is used to interact alongside Runtime organisation has facility to execute whatever rhythm out ascendence using method exec().
Here is the code sample which tin endure used to execute whatever native ascendence from JAVA.
final String cmd = "ls -lrt";
int pid = -1;
try {
// Run ls command
Process procedure = Runtime.getRuntime().exec(cmd);
} select manage of (Exception e) {
e.printStackTrace(System.err);
}
This is niggling overnice tip which tin endure really handy inwards to a greater extent than or less specific province of affairs simply inwards past times as well as large its non advised past times the really ain argue of making JAVA code platform dependence.
as pointed out past times Jaroslav sedlacek If non done properly it tin easily hang the application. Java as well as external procedure communicate through buffers. If buffer fills up, the external procedure stops as well as waits until coffee empties the buffer. Java app has to read both output as well as mistake streams of the procedure to foreclose this blocking. There is proficient util cast ProcessBuilder since 1.5 inwards coffee or apache common exec tin endure used too.
