Comparing String to int JAVA -

i trying figure out how make sure string variable not have number string. cannot import anything.

i have tried

namearray[i].equalsignorecase("")) || integer.parseint(namearray[i]) >= 48 && integer.parseint(namearray[i]) < 58

but did not work.

in java 8+, might use intstream generate range ([48, 58]) , check if string equal namearray. like,

if (intstream.rangeclosed(48, 58).anymatch(x -> string.valueof(x)         .equals(namearray[i]))) {  }

you mention want make sure doesn't contain value - perhaps want nonematch like

if (intstream.rangeclosed(48, 58).nonematch(x -> string.valueof(x)         .equals(namearray[i]))) {  }
