The code below will get the text from within the brackets. The code makes use of some String methods

String eDescription = 'This is (the test) text';
Integer openingIndex = eDescription.indexOf('(');
Integer closingIndex = eDescription.indexOf(')');
String textInBrackets = eDescription.subString(openingIndex + 1, closingIndex);

Using @Sovereigntys suggestion of using substringBetween then the code becomes:

String eDescription = 'This is (the test) text';
String textInBrackets = eDescription. substringBetween('(', ')');

The code below will get the text from within the brackets. The code makes use of some String methods

String eDescription = 'This is (the test) text';
Integer openingIndex = eDescription.indexOf('(');
Integer closingIndex = eDescription.indexOf(')');
String textInBrackets = eDescription.subString(openingIndex + 1, closingIndex);

Using @Sovereigntys suggestion of using substringBetween then the code becomes:

String eDescription = 'This is (the test) text';
String textInBrackets = eDescription. substringBetween('(', ')');

FYI: Both ways will find the first instance of '(' and ')'.

• Input: 'This is (the test) text', Output: 'the test'
• Input: 'This is (the test) (text)', Output: 'the test'
