Yes. Java supports labeled statements. You can put a label before a for statement and use the break/continue controls to jump to that label. ExampleSee the example below.Live Demopublic class Tester {    public static void main(String args[]) {       first:          for (int i = 0; i < 3; i++) {             for (int j = 0; j < 3; j++){                if(i == 1){                   continue first;               ...

| is a bitwise operator and compares each operands bitwise.It is a binary OR Operator and copies a bit to the result it exists in either operands.Assume integer variable A holds 60 and variable B holds 13 then  (A | B) will give 61 which is 0011 1101.Whereas || is a logical OR operator and operates on boolean operands. If both the operands are false, then the condition becomes false otherwise it is true. Assume boolean variable A holds true and variable B holds false then (A && B) is true.| is to be used during bitwise operations and || is useful during logical operations.

& is a bitwise operator and compares each operand bitwise.It is a binary AND Operator and copies a bit to the result if it exists in both operands.Assume integer variable A holds 60 and variable B holds 13 then  (A & B) will give 12 which is 0000 1100.Whereas && is a logical AND operator and operates on boolean operands. If both the operands are true, then the condition becomes true otherwise it is false.

The unary operator works on a single operand. Following are the examples of unary operators supported in java. Assume A = 60 and B = 20.OperatorDescriptionExample~ (bitwise compliment)Binary One's Complement Operator is unary and has the effect of 'flipping' bits.(~A ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number.++ (Increment)Increases the value of operand by 1.B++ gives 21-- (Decrement)Decreases the value of operand by 1.B-- gives 19

There are following boolean operators supported by Java language.Assume variable A holds 10 and variable B holds 20, then −OperatorDescriptionExample== (equal to)Checks if the values of two operands are equal or not, if yes then condition becomes true.(A == B) is not true.!= (not equal to)Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.(A != B) is true.> (greater than)Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.(A > B) is not true.< (less than)Checks if the ...
