Example of the use of the @Formatter:off and @Formatter:on annotations in eclipse to disable formatting for a piece of code.

formatter-annotation.java

public class Formatter {

    /**
     * The next piece of code is not formatted
     * because of the @formatter annotations.
     */
    // @formatter:off
    public void nonFormattedMethod() {
        int sum = 1 + 2 + 3 + 4 + 5;
    }
    // @formatter:on

    /**
     * Without the @formatter annotations the
     * same piece of code is formatted as below.
     */
    public void formattedMethod() {
        int sum = 1 + 2 + 3
                + 4 + 5;
    }
}
