get previous date in J2ME

I want to get the date of previous month in J2ME.

I have found this code :

Calendar c = Calendar.getInstance();  
c.add(Calendar.YEAR, -1); //one year back  
c.add(Calendar.MONTH, -1);// then one month

but this is working in Java SE not J2ME, please if anyone can help me find the corresponding method or class in J2ME?

Calendar does not have method add.

    c.set(Calendar.MONTH, -1)

Means you set value -1 at field MONTH. Your solution is

    // get current month
    int m = c.get(Calendar.MONTH);
    // decrement it
    if (--m < 0) {
        // if was january, must become december of past year
        m = 11;
        // set year to previous
        c.set(Calendar.YEAR, c.get(Calendar.YEAR) - 1);
    }
    // set new value "m" to field MONTH
    c.set(Calendar.MONTH, m);

Please refer to http://docs.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/index.html for documentation. You should't work without it unless you know all you need.
