8688327388	infinite loops	-if conditions never becomes false CAUSES: - syntax error -forgetting ending curly brace -logic error	2
8688327389	overflow	occurs when there are not enough bits to store a number	3
8688327390	counter	-incremented by a constant value useful for keeping track of number of times user makes a guess or types a password	4
8688327391	accumulator	new value is added to the last value initialized and decalred	5
8688327392	Sentinel, flag	constant that stores a value to signify that the loop should stop iterating	6
8688327393	for statement	executes set of statements a fixed number of times - for (; ; ) { }	7
8688327394	loop control variable	a counter to control the iterations	8
8688327396	increment operator	(i++) - increases value of a variable by 1.	9
8688327398	break (or breakpoints)	points in code were execution will be suspended	10
8688327403	string.length()	returns integer corresponding to number of characters in a string	11
8688327404	string.substring(int, int);	returns substring of string, starts at sarting position and ends one character before end position	12
8688327405	string.substring(int start);	returns substring which starts at start position and extends to rest of string	13
8688327406	string.toLowerCase();	returns copy of string with all lower case	14
8688327407	string.toUpperCase();	copy of string in all caps	15
8688327408	string.trim();	removes all leading and trailing spaces	16
8688327411	index	position of character in string (starts at zero)	17
8688327414	string.equals(String str);	returns TRUE when string is the same as str. returns FALSE otherwise	18
8688327415	string.equalsIgnoreCase();	same as equals() except differences in upper and lower cases are ignore	19
8688327416	string.compareTo(String str);	-returns 0 when str is the same as the string. - negative number returned when str comes after the string alphabetically. - returns positive number when str comes before the string alphabetically.	20
8688327417	string.compareToIgnoreCase();	same as compareTo() except lower and upper case differences are ignored	21
8688327418	string.indexOf(String str):	returns integer corresponding to the location of the first occurence of str in the string. Otherwise -1 is returned	22
8688327419	string.lastIndexOf(String str);	returns integer corresponding to last occurence of str in the string. otherwise -1 is returned	23
8688327420	string.startsWith(String str);	returns TRUE when string begins with str. returns false otherwise	24
8688327421	string.endsWith(String.str);	returns true when string ends with str. returns false otherwise.	25
8688394473	switch	a statement that matches a character or integer value to one of several possible cases.	26
