eclipse - Auto-align "=" in assignments

Question

How do one convert a block of variable assignments, e.g.:

private final String s1 = "10011";
private final String s2 = "01100";
private final String ones = "11111";
private final String zeros = "00000";

To a straightened format where all = signs are aligned to one space after the longest left-hand side, e.g.:

private final String s1    = "10011";
private final String s2    = "01100";
private final String ones  = "11111";
private final String zeros = "00000";
