Simplified Logical Expression of Java Code refactoring

Refactoring logical expressions can make the code more concise and readable, with the following common situations: 1. Multiple conditional statements: When multiple conditional statements appear in the code, the readability of the code can be improved by merging or simplifying conditional expressions. For example, the original code is as follows: if (a > 10 && b < 5 && c == 0 && d != 10) { // do something } The reconstructed code is as follows: if (a > 10 && b < 5 && c == 0 && d != 10) { // do something } By refactoring the code, you can see all the conditions more clearly and the code is more concise. 2. Nested logical expression: When there is nesting in a logical expression, you can simplify the code by using the extraction method or Logical connective. For example, the original code is as follows: If (a>5&&b<10) | | (c==0&&d!=5)){ // do something } The reconstructed code is as follows: boolean condition1 = a > 5 && b < 10; boolean condition2 = c == 0 && d != 5; If (condition1 | | condition2){ // do something } By refactoring the code, the logical meaning can be better expressed through variable names, making the code easier to read. 3. Repeated logical judgment: When there are repeated logical judgments in the code, the code can be simplified by using the extraction method or Logical connective. For example, the original code is as follows: If (a>10 | | b>5){ // do something } If (a>10 | | b>5){ // do something else } The reconstructed code is as follows: Boolean condition=a>10 | | b>5; if (condition) { // do something } if (condition) { // do something else } By refactoring the code, repetitive logical judgments can be avoided and the maintainability of the code can be improved. Refactoring logical expressions can make code more concise, readable, and improve its maintainability and comprehensibility.
