Task $3$: validString $()$ java

Write a method named validString that takes two parameters, a String $x$ and $y.$ The method should determine if$,$ after multiple character deletions in $x,$ the String $y$ can be obtained, e$.$g$.$ if $x=$ heeaalolo and $y=$ hello then after deleting the red characters from $x$ we can obtain $y.$ The method should return true in that case, false otherwise. Note that only deleting characters is possible; you cannot change their order.

Examples:

$\backslash$table$[[$Call$,$Return Value$],[$validString $("$heeaalolo$",$ "hello"$),$true$],[$validString $("$hlelo$",$ "hello"$),$false$]]$
