Remove specific char from String

Question

How To remove a specific Character from a String. I have a Arraylist testingarray.

String line=testingarray.get(index).toString();

I want to remove a specific character from line.

I have Array of uniCodes

int uniCode[]={1611,1614,1615,1616,1617,1618};

i want to remove those characters that have these Unicodes.

Can you give an example what you mean by _remove a specific character_ — Amulya Khare, Dec 25 '13 at 06:52

you can replace character using replace method in string.

String line = "foo";
line = line.replace("f", "");
System.out.println(line);

output

oo

If it's a single char, there is no need to use replaceAll, which uses a regular expression. Assuming "H is the character you want to replace":

String line=testingarray.get(index).toString();
String cleanLine = line.replace("H", "");

update (after edit): since you already have an int array of unicodes you want to remove (i'm assuming the Integers are decimal value of the unicodes):

String line=testingarray.get(index).toString();
int uniCodes[] = {1611,1614,1615,1616,1617,1618};
StringBuilder regexPattern = new StringBuilder("[");
for (int uniCode : uniCodes) {
    regexPattern.append((char) uniCode);
}
regexPattern.append("]");
String result = line.replaceAll(regexPattern.toString(), "");

Try this,

String result = yourString.replaceAll("your_character","");

Example:

String line=testingarray.get(index).toString();
String result = line.replaceAll("[-+.^:,]","");

replaceAll("[-+.^:,]","") - this is working as a regEx and if anything is present in line , it is replacing with blank( trimming it). – satender Jan 09 '18 at 15:02
